Right i thought so, so it needs to be timed with the tdc mark then.
Well, for some strange reason, when i line that mark up and take up the belt tension, because theres a bit of slack between the crank and intermediate pulleys, the crank moves while it takes up that slack and therefore puts the flywheel out a bit. It just WILL NOT sit right at tdc. I can get it in line with the 6 degress btdc mark, but NEVER the tdc mark.
Does anyone have any ideas or seen this problem before?
