    Speed wings and bush tires....

     

    I just bought a MkIV with Speed wing and intended to look for HH wings. I want a bush plane, but it looks like your doing all right at 1000FPM?  Would you suggest I just run it as is and not hassle with finding a new set of STOL wings?

    What the going labor rate per hour these days?

     

     Im in SoCal and I'm considering taking the 16 hour Rotax rebuild class at California Power Sytems. I'm wondering how much, if any in the hole I'd be, by dropping my Avid off, and having a shop do the work like you chose to do.  Part of me want to learn, but the other part of me wants to ditch the 2 stroke in the future. I dont know how prudent it wiuld be to have the rebuild know how under my belt if I mive away from Rotax 2 strokes.

    I agree with Tom. Leaks are the big thing to watch for. I flew over the airport for 45 mins in mine after my Rotax Rick overhaul recently. I couldn't stand it much longer then that and went and found a field to land in. I have heard various ways to break in a new motor but as a general rule on a two stroke just run it. I was pretty nice to mine for the first two hours as far as cruise power settings go. I used to rebuild my 2 stroke race bike on Friday night and race it Saturday morning. Before I sent my engine of to Rick I pulled all my jets and visually verified the size and wrote it

    I think with the age on the engine, new seals and a complete inspection are in order.  I had a 582 that had quit on the guy before I got it.  Seemed to run okey afterwords.  When I tore it down you could see the scuffs on the pistons but couldn't see them before it was tore down.  I had to get it bored out to the next size.  The guy mentions that the rings were stuck and he had the heads off.  Did he actually pull the cylinders and do a proper decarbon job?  After he gets the engine gone through, then make sure the filters and carbs are clean .  Stock needle jet and jet needle set maybe 1 step leaner than stock setting, and probably 162 main jets to start with.  CPS has a chart in their catalog that says what settings should be at different altitudes.  Just my 2 cents, after flying behind at least

    a dozen different two strokes, half of them at least my own.  Jim Chuk

    Sorry, you mentioned in your blog or on here that the owner of Semonini returned your email or call. Thats the contact Info I was  looking for. I Used thier website to find the US distributors contact info and wasnt so impressed with thier responces to simple questions. The owner of Simonini is who Im looking to talk to next.

    Would you mind passing the owners email or contact info to me. I've talked with the US rep and wasn't so impressed.

    1) It the STOL performance better than the Rotax 912?

    2) How much lighter is this combo than the 912?

    3) Im guessing the torq isnt there but the HP is in par.

    Who's the go to Rotax guys in SoCal?  

     

    My new to me motor has 20 hours on it but has been sitting for 20 years and want to have it gone through before I fire her up from hibernation.

    That thread fell flat.

    1) Inquiring minds want to know if the carb cleaning did the trick. Did you get the rough idle worked out?

    2). Is the 582 enough power for you? I'm in the same boat, and the price point of a 2 stoke Avid is very appealing. I'm digging deep to find a clean Mark IV.
