allright so ive got spark and the motors runnin pretty good except cyl 3 isnt firing, i unplug the plug wire and it arcs to the head so its getting spark, i think it might be timing related, if i goose the throttle it blows fuel back threw the carb so im guessing the intake valve is still partially open on the up stroke, you think i should jump the cam a tooth on the chain? and if the valves open on the intake wich way should i jump it? also the dist is all the way advanced it wont run in the middle (or run as it is in the middle) thanks guys

 

well figured it out, one of my rockers were way out of spec, got them all within specs (they were all off a little bit) and she runs like a champ thanks alot guys for bareing with me threw all the dumb questions
