I have a problem. My Webra 50 runs great, except for one problem. It always want to lean out a lot. It weird. Cause when i get ready to tune it,i tune it, and then i pinch the line and make sure i set it right, and the pinch test works out. But anyway, in the air, it ALWAYS leans out really far and the engine goes to idle like its gonna quit, then i save it by throttling back. The i let it fly for 3-4 seconds then go to a high throttle, then it leans out and keeps doing that. I richen it up a ton and no difference. I think its a problem with the carburator, and it not drawing the fuel it needs. Look at the pictures and tell me what you think please.
