I had a small crash on Saturday. Put the heli back to together today and test flew it. Had bad vibration. Shook my MPII loose and my fly bar carrier. Replace main mast and spindle. Ran it up again. Vibration was gone. Now my engine went lean. Real lean. Like at one point I think it 250 deg. I had to turn out my high and my middle needle. High is out about 4 turns and middle is out about 2 1/4 turns. low stayed the same. What might be wrong. It was fine and now it's not. Would a hole some place cause this?

Is your muffler pressure nipple clogged or bent or sonething? Have you checked your fuel filter for crap? Have you made sure your clunk lines were not kinked or twisted or anything. Next pull the carb and blast out all the passage ways with alcohol.
Congrats on a SUPER fast rebuild. you got the best looking Raptor I have ever seen Matthew!! :)

Thanks Will. I'll have to do all that now. Yea only took a little while. Hey I email MAH and we don't have to drill holes in the blades to make them fit you can order them with 5 mm bolt hole all you have to do is ask. Any way I pushed the bushings out of my TT blades and drilled out the MAH blades to fit and knocked them home. Worked nice. Back to my engine. Might be something in my carb. It went down in the tall grass could have socked something up.
