Sammie is running, still funky. currently, after getting engine at TDC with the finger, the crank gear is pointing straight up to the mark. the camshaft gear mark is pointing straight down. it cranks and runs decent. The book says the cam gear should be pointing straight up,,Can i roll cam 180 and get the mark up top and re position the distributor to aim the rotor at #1 plug, will this work. or ?
