Ok, this is actually for a friend of mine's Pathy, but here goes. He came over wanting me to change his rotor and bad plug wire that was shorting out on his hood (OUCH!) So, we did it, and his rotor was stuck on, and with lots of prying we got it off, but the metal piece that screws into the shaft had separated from the rotor. So we take out the middle screw that holds the distributor rotor in line with the distributor shaft, and knocked it out of time, (sort of forgot to mark the position, my bad) So, we've tried timing it by the crank marks, putting the rotor on at the middle mark on the crank, to number one cyl. No go. Tried timing it to my pathy's timing to the crank. No go. Tried both posittions, one, it back fires LOUDLY as if a gun is being shot, the other 180, just turns and turns to no avail. Any ideas?? Any help is GREATLY appreciated. Thanks!!!!! He already had to miss a day of work because of this..oops. I've done all i know what to do..
