re: top dead center with a dowel question



One way to be sure the mark is actually TDC is to use a dowel or screwdriver 
or some other solid object in the sparkplug hole. Then hand crank the engine 
one direction until it is almost at TDC and hits the object. Make a mark on 
the balancer where it lines up with TDC pointer on the engine. Then without 
moving the object hand crank the engine the opposite direction almost 360 
degrees until it hits the object again. Make another mark on the balancer 
where it lines up the same TDC pointer you used before. The two marks you made 
should be equally on either side of the TDC mark on the balancer. 
Know what I mean? :)
