....

ran great before, why would the the timing be bad now? it didnt change

the dude has the distributor adjusted all the way toward the radiator

He could have been off a tooth when he put the dist back in....had to crank it all the way to time it right.

My timing keeps changing also I had the upper cam seal replace along with the timing belt I think the mechanic may have moved the upper cam pulley a little bit my dizzy is almost all the way to the right when your looking straight down it.

sounds like a tooth off to me
