RE: OS Max 55 AX issues
The reason i dont run castor is because it makes brown messy residue, that is as i remember from my flying days in the 90's maybe it was a higher percentage of castor oil that i used, cant really remember what fuel i used.
yep 3 full 360 rotations. lines are new, clunk was taken out once, but taken care of, put back in without damaging it. will check it again. dont think its the issue, but will do anyways.
it doesnt really do the 4stroke burble sound. I just need to do the pinch test and see where it is at. might take motor off and put on the test stand.
