My Posts This: Topic Forum | The list is long on that one. 1st check all fuel system lines, especially the clunk line inside the tank and the brass lines going thru the tank bung. Honestly if I didnt KNOW all the lines were 100% good, Id go ahead and change all of em, $5 well spent. 2nd, overly rich mix can cause excessive vibration and weather change necessitates tune adjustments, so that could cause it. 3rd, change the main blades to a known good set. Then maybe but unlikely a torque tube bearing and or bad bearing in the tail assembly. After that, you are looking at a frame split, bent or "spun" shaft, and/or a bad bearing. Items 1, 2, and 3, are most likely the others fall in line with easiest to eliminate. Good luck with your search, some times these can be a real pain to track down. If you are not running a header tank you might want to consider installing one if only till you can get this tracked down. A header tank will help protect your motor from needless leaning in and out due to air in the fuel.
Its gonna be a process of elimination so you need to get into the mind set of KNOWING for sure each possibility can not be the problem.
Of course some times you get Lucky and its the first thing you check!
