I am getting spark and fuel injector signal to #3 cyn but no combustion, wile running I can pull plug wires 1,2 and 4 and causes engine to stall but when I pull #3 I notice no diffrence in the running Idle at all, this isolates it to cyn #3 so I did a compression test and it tested at 120 lbs
could a condition exist that allows you to get normal compression yet not allow air intake for proper combustion? like a stuck intaKE valve?
gonna try to see if it's a broken rocker arm maybe a broken retaining pin or ring? anyone have a clue what I am looking for? will it be obivous?
I am delaying pulling the head and cam as a unit and taking it to have it machined, I have limited funds so really trying to fix it myself. by bicycle I have most parts stores withing a reasonable distance. I know I can do this, any help will be a life saver Jimbo....
