582 Exhaust joint leak fixsEver since I switched to my Blue Head my exhaust joints have not lined up as well as they could have. I don't know what the difference was between the two engines but the alignment ended up slightly different. This has caused me to battle an exhaust leak. I'm pulling my exhaust manifold to inspect my pistons and rings as part of my Condition Inspection this year and I want to do something about this leak before I put it back together.
As you can see in this picture my muffler is mounted to my firewall using rubber isolators. These came from McMaster Carr. I'm planning on getting a few that are 3/4" of inch longer to try and get a better angle on the joint.
I've already taken it apart twice and cleaned up the joints and tried to adjust it to where it would seal up with no luck.
Leni I know you've used valve grinding compound before. Did you just smear it all around the joint and then just work it around in a circle? What's the best way to get it to actually grind the high spots?
Another thing I've considered doing is going to the ball joint conversion kit. I safety wire my springs and have only ever had one break before. At $140 to do both joints this conversion is pretty spendy. It would be worth it though it though if it'll seal up the joints better.

Any other techniques that people have found that works to seal them up? I thought about replacing the elbow until I saw the price of one!!

Have you had any snow? We were in Soldotna in July and we had a few good days and some rain. Mosquitos were down too. Great time.

mtgsxr added a post in a topic Looking for Avid or Kitfox with 912
Flies GREAT! as expected.... I don't take off or land yet myself Had very dirty carbs due to sitting with auto fuel. could only get 5000-5100 rpm before it started sputtering.. but that was still plenty of power for most flying.. prob only 54 hp @ 5000..lol I rebuilt carbs and am working on all fuel and coolant lines. radiator is getting cleaned & pressure checked ect.. P.S. I will be a Evans coolant dealer in a week or so.. discounts to fellow rotax flyers. e-mail me at russ@lelandshondasuzuki.com if interested.-

The carb mid range circuit out of adjustment will cause it to miss at those RPMs.
Here's a short "Hints for Home Builders" that gives an overview of the carb circuits. Then under that you will find short videos on how to inspect and adjust each circuit...Enricher circuit, Idle circuit, Mid range circuit, and main jet circuit.

582 missingGuys,
I'm coming to like the 582 now after about 10 hrs. I still have a miss or roughness from idle up to about 4500 rpm. It may still be there at TO and cruise power but Im just not noticing it. Temps and EGT at TO and cruise are good. The all the plugs look good, I've syn'd the carbs etc. but nothing seems to help. It appears worst on the left ignition that the right but it's hard to tell. Any suggestion as to where to start hunting ?
thanks,
EG

ps anyone looking for some Lotus floats, I think they are 1250's I know where that are a set down this way that probably could be had for a good deal

I have a model 2 Kitfox.
I will refer to your friends Avid gear when I call Grove.
I was under the impression that the gear attach points on the early Avids and Fox's were the same.
If that is true, maybe Grove does not know that and that is why they say I need a custom gear and I need to make my own attachment blocks.

c_stauffer added a post in a topic replacement wing tanks!
Hello all,
I'm a newbie here and have an avid that is leaking. Big surprise huh? I have been reading all of the posts about fixing VS replacing and I have a few questions & was hoping some of you could offer your opinions. The plane has a heavy hauler wing with 13 ga tanks (2 tanks in each wing). They are metal so from what I gather, I'd be wasting my time fixing them as they will just leak again... So, replacement is the way to go... My questions are regarding the removal & replacement procedures. How much of the wing will have to come apart? Will I need to uncover the entire wing? Basically, what I'm asking is, has anyone gone through this swap before and what were some of, or all of the issues encountered during the process. I do have access to ethanol free gasoline & that is all I have used in my other Rotax engines with no issues. I do premix. Any help would be greatly appreciated.
Respectfully,
Cory

It's because of my E gearbox that it looks that way. Most of the early B models you see had 532's with B boxes that would hide inside the cowl better.

He took delivery of the gear about 2 months ago. It is brand new.
It is the Avid Mark IV gear with the extra height added. Listed here. He requested the additional length. Not a big deal.
What model is your Kitfox?

Would I be able to get contact info. for your friend with the Model C Avid to find out what he went thru to get Grove gear.
You friends swept forward gear looks like it would be what I need without having to weld on forward float fittings.
I am curious when Grove made that gear for him because they act like this is a new idea, not usually done and I would have to manufacture my own attach brackets.
Thanks Herman Oregon 541 404 6464

My gear is no problem - Got Kitfox 7 Grove with nosegear - Just cant follow the attachment using the stronger bungees as a substitute for the cables on the regular gear - Just bugs me when I don't understand something - might even drive me to drink - or is that, drink to drive? No-No! EDMO

Ed - I prefer Kessler and diet Coke...
My buddy used the Grove gear on his C model Avid fuselage.
I don't know if this will work on you fuselage, but he sure loves it. Far and away better than the oem or the Airdale "bush" gear that he bent. This is a custom set from Grove, 3" taller.

It sure didn't work for me - I am not a member - Just an old clutz on the puter - maybe some young mind can find it and post it. Been thru 32 oz of Michelob - out of Bud Lite - and still cant get beyond "horizontal", which I understand is not "vertical", but cant for the life of me, figure out how in hell he attaches these stronger bungees. I have the Grove gear, so don't really need it - but it is something that I don't understand, and that is frustrating - and I might want to pass it on someday.Thanks,

Can you also post the drawings he referred to on the Yahoo site - My old mind tried its best to figure out what he was describing on the horizontal bungees, but the hookup remains a mystery to me.

Paul thanks for sharing the Yahoo messages regarding alternate bungee backups and
Av8r3400 with the real world Grove weight increase.
I was told about Airdale's swept forward aluminum gear that is available for Avids that would work for a model 2 since I do not have the forward float attach points for the grove gear like model 4's have.
Any body have experience with the Airdale swept forward gear?
I contacted Grove with measurements and they are working up a bid for a custom swept forward gear for my model 2.
Grove told me they are not excited about how much forward sweep is required and will the longerons handle the the loads.
Has any one on this forum welded on forward float attach points and the fuselage reinforcement bracing that would be required?
My stock model 2 gear places the axle 2.5 inches forward of the forward attach point as it is.

So where do I get an Avid cowl?
Are there variations of the Avid cowl by year or model?
Joey. It seems like your cowl is more abbreviated than most or is that only the front part that would normally cover the gearbox?
Thanks Herman

When I had to fix my truss, I took the down time to switch to Grove, and never looked back. Far superior in every aspect. Overall weight gain was 12#. I took that as a hint to loose this weight off my fat ass.
I also upgraded to Grove wheels and brakes which are also head and shoulders better than the cobbled ATV wheel and Matco brake garbage that came on the plane. Now I even have brakes that will stop the plane!

Herman I don't know if you noticed this on the Yahoo site but it looked interesting as an alternative to the cables.
This is message 36437 on the Yahoo site
Those comments on the wire as too hard a stop, the proposal of an additional bungee-cord loop with a stronger cord, that all is quite interesting An idea I am elaborating is to make an additional bungee loop but one that ties horizontally both landing legs just below the cockpit floor. The good thing about that is that with usual, not to big inflexions of the landing gear, that bungee loop nearly does not get extended atall, this, is, it makes almost no additional force even if that bungee cord is very strong. Only when the deflection is quite important the bungee starts to work but very progressively, linearly. I have written down the equations that describe the force delivered by this proposed bungee of mine and I am analyzing the way it works a bit closer and hope to be able to give a quantitaive description in two or three days. This notice today is just to hear if someone has implemented such an idea before and if yes, to hear what his
experiences have been with it.
Cheers Juan
Something to consider perhaps. I am using the HighWing Bush Gear and am happy with that after a little work to the truss and fuselage sides to beef them up.
Here is a better explanation in message 36444:
In that question of protecting the fuselage of he Avid against damage at hard landings there has been made the proposal of replacing the security wire loop and also the proposal of substituting it by a loose loop of a much stronger bungee cord. This proposal makes at first sense but I fear that in reality it will be very difficult to find and install bungee material suitable for the task.
My proposal is a different one: remove that wire loops and add to the landing gear an additional "suspension mechanism" in this way: install loops of bungee cord placed horizontally below the cockpit floor, each loop passing through the space delimited by the horizontal tube of each landing leg and the stiffener running down, this is tying both landing legs together.
I have written down the equations describing the behavior of such a suspension. The results are described with the attached graphs. In those graphs the X coordinates is the deflection of the landing gear given in degrees. The Y ordinate is the vertical force ("weight") on the landing gear originating this amount of deflection. The redline is the relationship between force and deflection with the standard Avid landing gear installation. The black line is the additional effect of my proposed mechanism. The blue line gives the result of combining the two suspension loops.
There are two graphs the photos of them I have posted to the Group in a file "Ne Suspension mechanism". The one where the lines run more horizontal, this is, where the suspension is softer, corresponds to adding "my" loops having the same elastic values as the standard bungee cord loops. The other graph corresponds to adding "my" bungee loops with stiffness 3 times higher than that of the standard bungee cord.
The interesting thing is that "my loops" do not appreciably contribute to the suspension below 15° deflection. Beyond that point they progressively contribute to stiffening the suspension. A very positive point, I think, is that the elastic properties of "my loops" can easily be adapted by just adding loops as needed or considered convenient. Last not least is is a very positive point that the force created by "my loops" is a compression force on the stiffener of the cockpit floor. This means the bending forces on the stiffener remain as before, the new mechanism charges on the same stiffener but with forces running otherwise. In total the stiffener is charged in a more convenient way, less prone to damage it.-
