Tiger the timing on these can't move, the flywheel is located on a flat on the crank. When I get a chance I will pull one apart and see what I can find, thing that concerns me at the moment is the $15 price tag on the lower crank seal, not sure if this is Victa specific, I'll take one up to the bearing place and see if they have that one, a seal that size should be worth no more than $5
