Same hear, I surf at work on a T1 line. Spent at least 30 min jacking around adn found very little info.
I thought the the same as troy curt but it doesn't make since as to why the third cylinder in the cycle would be blowin down. It should be filling. Unless the firing order was other than 1,2,3,4,5,6.
With the 1 on C stroke, 2 would be E and 3 would intake,4 on C, 5 on power, and 6 on E.
Roll the engine over 180 and 1 is on intake, 2 on C, 3 on P, 4 on E, 5 on I and 6 on C.
Should I try adjusting all cylinders according what's outlined then worry about 3 exclusively?
I think my head hurts.
