distributor is placed wrong for timing
take cap off unbolt distributor lift enough to turn rotor place back dont bolt litely just enough to hold distributor down without it poping up on you
place cap back on
now you need manual start and kill switch up in engine compartment turn vehicle over with manual starter switch if runs rough turn distributor till sounds good now time it with radar gun tighten bolts the rest of the way
now for what i described this has a margin of error going 1 to 3 notches to time in either direction from front to back or back to front turning of the distributor rotar
i hope i had made some sense here
or counter clockwise the lifting distributor and turning rotor one tooth to engine crank this is timeing
