With all marks lined up and at 0 degrees , truck will not run . Can turn distributor all the way to right and barely will run so leads me to go over a tooth on the rotor in distributor . Well it will run but not hitting on all cylinders , very weak . And with timing light the mark is about 27 30 degrees to forward. I’m went round and round with this and I’m jus about ready to grab some gas and a match lol. Joking of course. Any help would be greatly appreciated. I’m bout to take the crankshaft pulley off and check.
