When I removed the flywheel (129 tooth model) from my engine I did not mark it's position on the crankshaft. Will I encounter a problem when I put it back on if it is not put back in the exact spot?
Ken,
The flywheels were originally balance with their respective crank shafts. So you could loose a little in the balance department. Most 129 tooth flywheels did not have any timing marks on them. Try to look closely for a pair of punch marks or scribe marks that may indicate original orientation.
