Well i took my plane out yesterday to fly and halfway thru second flight the studdering or bogging or whatever you call it just cleared up and it ran like stink. I then had some real fun with it as always before it would run great on ground only to get overly rich in the air.So here i am having a blast now but not really figuring out what had changed to make this thing now run so great. Well in finishing up i noticed a chge in pitch of engine so i set up to land but went deadstick , I was able to land with no probs. but upon refueling i saw my PLASTIC carb mount had let go. Now this engine was sold to me as a version 3 which i have deduced is supposed to have a twister style metal carb mount. Any ideas? Oh BTW i think the vacuumn leak is what made it run so great all of a sudden.

look at my posts in the DL 50cc thread, page 54, post #1344. Read in about a page after that.

hope this helps

First thanks for the reply. Did this help with your stuation? Seems like alot of guy's must have this prob. And not only with the engine i wrote in about so i think i'll be trying that little trick.
