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.

Guys,

 

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,

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 

Cory go to the wingtanks.com home page and see my install pictures.  Only recovered the tank section of the wing.  Russ

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.

 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,

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

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?

Av8r3400

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.

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.

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!

You're not supposed to see over the nose on real airplanes….  

 

 

Ed, not sure how to get the photo from the photo section on Yahoo.

This link is the best I can do but you will probably need to be a member of the Yahoo Avid site to follow the link.

 

 

Ok, that did not work but if you are a member over there you can go look in the photos section.  Maybe somebody knows how to get photos from the new Yahoo site but appears over my head.

 

One more try:

This one works for me, hope it does the job for you Ed.

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,

Paul,

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.

Thanks,

EDMO

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.

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:

 

Are the Kitfox and Avid landing Gear safety cables an asset or liability?

When metal hits metal things bend or break.

After 18 years of not having to weld on  my Kitfox,  I bent the bungee truss under the seat.

The gear legs and longerons were unharmed and I was able to fly it back.

Joey told me that he has removed the safety cables on his Avid for this very reason.

I mention this only for other Avid and Fox owners to consider to hopefully prevent what happened to me

I do not like flying without Safety cables even though I have not had a bungee fail.

If going with safety cables again, I would make them as long as possible to keep the airframe out of the dirt (maybe not the prop) or how about a second set of bungees wrapped loose over the primary bungees to act as a progressive suspension and act as a safety ?

 

TIME TO GET THE SAWZALL, TORCH, GRINDER AND WELDER OUT

 

 

Awhile back I asked about Grove gear. Is it time for grove gear?

Thanks Herman

 

 

 

Don't have a measurement Herman but having flown both the over the nose visibility is much better in an Avid. In fact in cruise you have to make your visual reference look like you are nose down slightly to keep from climbing.

It appears that the Avid top cowl is lower on the windscreen than the Kitfox top cowl piece which would give better forward visability.

I am considering replacing my Kitfox round cowl with a smooth Avid style cowl even if it means lowering the 582 or turning it upside down Avid style.

Does anyone have their Avid nearby to get a vertical measurement from the longeron on the bottom of the fuselage to where the cowl meets the windscreen?

Are there any new or used Avid cowls available?

Thanks 

Herman

 

 

 

Well after another day in the hangar going through the squawk list we put it in the float pong yesterday and flew it out to the hangar so its home now!  wings were 17 gusting 27 but straight down 1W so take of was quick even though I was just taking it easy on the first TO.  Hope the rain lets up and I get to put a couple more hours on it today.  The water level in the lake has come up almost 2 feet in the last week from the rain.

 

sweet!  I like the paint!  Let us know what you think of it when you fly it.

 

Here's one, a little bit of a hop for you though in Western NC.  There are several Kitfox's & Avid's in my immediate area but they choose not to be online.

A few pics of the new V8 LS1 Drivetrain and Suspension Assemblies.  Unfortunately I forgot pictures of the tubular control arms, sway bars and end links.  Oh well.  I'm hoping the Miata sheet metal can handle to torque.  V8 Roadsters recently had a chassis failure which concerns me a little
