"86" f 150 timing

[bigball]

Hey guys! I need help. I tried to set my timing but when I put the gun on it, it seems to be out of wack by atleast 3 inches. But I can burn rubber from corner to corner. Is that bad on my chain?

why are you setting timing if it runs ok????????
to set the timing you need to unplug your timing connector. it is a little grey or black connector plug located near your dist. or remote mount tfi module. set timing with it unplugged, then plug it back in. when you un plug this, the pcm does not control your timing.
