So my dad bought this 81 cb750 a couple years ago and he always had trouble with it, so he gave it to me and we find out that it was only running on 3 cylinders, cylinder one wont fire, so I replace all the spark plugs, still not firing, so i removed the spark plug on cylinder that is not firing and the spark plug look like new compare to all the other! I have a spark but it dont seems to hsve fuel going.. I've check the compression and i got around 120 psi on each cylinder, i need some help for this one, thanks!
