timing marks/TDC
Posted: Thu Jul 15, 2010 2:36 am
I find it really hard to find TDC on the rear cylinder to set the ignition. Tried the "feel the piston" method, but that gives me +/- 5 degrees or so accuracy.
Shouldn't it be possible to use the timing marks on the beveldrive for this ? I know they don't align at TDC, but does anybody know exactly when they align ? Then I guess I can set the degree wheel after that....
Also when I put my engine together, I followed the manual to every detail, but couldn't get the ignition right afterwards.
Turned out the cams were 180* off. The timing marks of the bottom end line up every 3 turns of the crank, but all the marks (including those of the bevels) line up only every 6 turns.
Did I miss something putting the gears together, or is it a hit or miss operation ?
