    I know you are very new to working on 2 strokes, and we will see what we can come up with to help get you back in the air. Nothing is more frustrating than working on an engine to only have problems...

    You never said if sealant (proper crank case engine sealant) was used between the case halves. The only thing that will make a 2 stroke run hot like that is a lean fuel mixture, be it too little fuel, or too much air due to a leak and timing.

    I am sure you have already run through all of this, but just double checking (because I hate the jumbled up mess of the posts on the yahoo groups site that makes it hard to sift through the info).

    Check Carb boots for cracks. Rotax Carb boots suck. JBM Industries makes a much better boot with a better rubber compound that lasts much longer. Click here for JBM Industries

    Primer lines OK, or if not used the caps are in good shape and sealed well.

    Rotary valve timing is correct. The third I did I was looking at the book (engine right side up) and working on an engine that is upside down... I timed it to the wrong cylinder. Didn't run too good!

    Carb bodies cleaned out. Pull the main jet and make sure there is no blockage, even the tiniest hair.

    Plastic screen that goes over the main jet was not damaged when the float bowl was put back on.

    Float level set properly.

    Did you mess with the in flight mixture on the cylinder that was running hot. Crank that open a turn or two. My plane normally runs one cylinder a turn richer than the other to keep the EGT's the same.

    Bad plug wires should make it pop snort and fart or not run at all, but I can't see it making the cylinder run hot.......

    Hey, just thought of this.... You changed the stator correct.. did you change the trigger coils are they the slotted type that you can change timing on, or the fixed round hole that you can only adjust gap??? If one of them is off, I can see it hosing up the EGT's, and you will really see it at high RPM as it does advance a small amount with the Ducatti ignition.

    Let me know what you have done so I can rule out issues in my mind and see if we cant get this bugger back in the air for you!

    I would be tempted to send a large burly Italian guy to kick Jack in the ding ding for giving out some bogus advice for free It's all good, and we will see what we can think of with the aide of a toddy or two to help you out!

    So what to you think Joey, am I outa my mind on this one I was sitting in the garage this AM and thinking about this and a little light bulb went off in my head... A few quick turns of the wrench walla.. kills the main theory over there in my mind

    Below is a cut n paste of what I put on the yahoo groups, but here I can post the pics (nice thing about the forum based systems....


    Joanne,

    On the plug test, we will warm it up with old plugs, shut down, change to new plugs, start and go wide open for 20-30 seconds and kill it with no idle down.
    This will show the top end only burn which is what you are interested in right now.

    I think you have a B box correct? I just pulled one apart 2 minutes ago just to double check myself (and I am a sucker for ladies in distress) and that front
    seal is bathed in gear oil correct? The seal is right behind the pinion gear, and it is lubed with gear oil, therefore, the front seal would be in gear oil if
    I am not way out in left field chasing alligators ( i'm not cause I just checked it). If the front seal was leaking, you would be sucking gear oil into it. To
    get air around that front seal, it has to pull through the gear box, and the oil that is bathing the gear... damn near impossible.

    Has gear oil level gone down? Can you pull the vent on top of the gear box and put a slight amount of air pressure to it and see if it holds? I am not
    sure that vegas would be giving odds on sucking enough air through the front seal and gear oil to give you a high reading, unless it was a catastrophic
    failure, in which case you would be burning gear oil and would darn sure know that smell and the cute little blue cloud of mosquito killer coming out the
    exhaust.

    Lets think about the WD 40 trick lock wood had you do. Remember when your gear box was leaking due to the pinched oring? That is what seals off the gear box
    and front seal chamber from the block.

    Do you know how to get WD 40 from the little hole in the side of the gear box that you shot it into, to the front seal to see if it is leaking... It is the
    same way you put an elephant into a shopping cart. You take the S out of safe and the F out of way.... your right there is no F in way, unless the rubber
    oring was leaking also and you would know that by gear oil running down the engine again and blowing out the two tell tale holes in the side..

    When the case was split were the two mating surfaces cleaned, then was a sealant applied to them correctly before re-assembly?

    I am leaning more towards the carb boot leaking, a cracked primer line (if you use a primer) or a leak between the crank halves, or oring on the crank on the
    bearings (which you cant change without splitting the crank)or something plugging off the main jet and high speed circuit. Fire it up, then squirt WD 40
    all around the mating surfaces between the two case halves and see if it picks up any RPM or it may even choke it down if the leak is bad enough.

    You can pull the gear box in about 5 minutes after you drain the oil and get direct access to the front seal.

    I will post up pics on my avidfoxflyers site in a just a few to point out what I am saying about the front seal and trouble I am having thinking that it could
    actually be the culprit.

    Leni



    Front seal and the oring that seals off the chamber you shot WD 40 into..



    Another shot of the same



    the groove that the oring seats into showing the elephant into the shopping cart thing....



    One more shot just for good measure.

    That reading is alot closer than the others I have seen. Mine was about 1500 RPM off on the top end, but bottom end it was pretty damn close.




    Cool, it is a bit boring sitting on the ground for an hour with a stop watch and clip board, timing and writing numbers.

    SWEEEEEET. Good feeling to have the bugger back in the air and ready to go huh! Getting ready to head for the hangar and get my ski's put on Wagonmasters Mk IV so we can fly out to a buddies cabin for a few days. Should be a good time hanging out, chasing 4 legged critters, and just fun flying in general!

  9. akflyer added a post in a topic my mod C   


    I had some epoxy primer left over from painting all the steel parts inside the wing so I slapped it on all the new wood.

    Replacing the rib tails was pretty easy! Just use a heat gun to soften up the glue, and a putty knife to separate the cap strip from the rib. The first wing I did, I used the measurements out of the book and they did not line up perfectly with the flaperon when I went to hand it. The second wing, I clamped the flaperon onto the tails, then using a 12' aluminum "I" beam, I lined the cap strips up, then glued them all up at once. The second wing came out perfect.

    Do you need to replace the cap strips or just the tails?

    You can also use a good spar varnish on all the new wood to seal it up.

    Well Duuuhhhhhh... I thought you had already shipped the GH back. The original setup does look better, but the other would have worked with no worries! When I swapped over the belly radiator, I had to do some creative copper work to get it all hooked up.

    If all goes as planned, I will be picking up the new sled tomorrow and starting my little engine swap project.

    That is how mine and a couple others here are plumbed. No issues with leaks etc.

    Looking at making a couple sets. The 4130 alone will run about 300 a set. I know there is not 300 in aluminum on the skis that Jack showed. It would be a shit load faster to cut and rivet together the aluminum, than to fit, tack and weld out the 4130. I am gonna look at the plans and see if they are as simple as they look, get a material list and price it out. If it ends up being real close on price, I guess it will be a coin toss

    Looking good! The outlet and hose are 1"!

    I think lifting the tail may get some more air out of the system.. I could be wrong... There is a little casting in the block in the grey heads for sure that will trap a little air in there unless the entire engine gets angled down. Will be easy for you atleast try it if you roll it outside and pick that tail up about as high as you can get it. The blue head may have had that dam removed but I am doubting it.

    That paint for the gear box looks DAMN good. It also looks like you Y pipe has not been modified and put up at a steeper angle. No issues with it not rubbing inside the cowl? Can you get all 4 bolts in each flange or are the top inside 2 impossible to get a bolt in

    Keep the progress up and you will back to flying tomorrow!

    Yes I did, that may swing me as they look like they will be easier to build! Not to mention the price of 4130 has gone way up since the last time I bought some. From the pics, it looks like Acrolights modified just a bit for more width would be real easy and cheap to make. I would make the pedestal a bit taller to get better angle of attack. I will be real interested in seeing the plans when I swing by!

    Mine is 5/16" from wing tanks to the gascolator on the firewall, then 1/4" out to fuel pumps and carbs. My brothers old KF II was 1/4" the whole way.

    Trail Lake Lodge in Moose Pass makes a mean burger! If we get some snow, Skwentna makes a good burger to.

    I will call trail lakes and see if they are open all week now, or just on the weekends.

    Careful what you ask for
    After a relaxing bath Monica Lewinsky was looking at herself, nude in a mirror.
    Her frustration over her lack of ability to lose weight, was depressing her.
    In an act of desperation, she decided to call on God for help.
    'Lord.... If you take away my love handles, I'll devote my life to you,'
    she prayed.


















    And just like that... her ears fell off .

    And that is why this site is here.. I wont take advertising money etc, so I dont give a shit about what is said about a particular design, as long as it is relatively factual! Unless a person is threatening to go to someones house and beat their ass, I wont mod a post (Laugh, I know of 3 times this has happened on a snowmobile forum I hang out on).
