man I am still having trouble with .28 still has the stall problem when motor gets in the upper revs, carb started leaking also leaking from brass pinchers that hold the carb. so I sealed the carb and holders with some silicone. thought that may have been the problem. its very strange when motor leans out on its own at the very end of the tank it doesnt die when reved but if I try to lean it out with the needles it does. i am so lost. could the needles be bad if so where can i get some new needles and an oring for the carb. also what are the factory settings for the needles
