Need help with the next step. Suggestions please. Today I was determined to trouble shoot the irritating intermittent missing or poofing in the exhaust. I have narrowed down my problem to the #2 cylinder. I replaced the spark plug and did a spark test. Good spark, greater than 1/4 inch. I attached the timing light to #1 cylinder and that was at 4 degrees at idle. So timing "appeared" to be good.
I then checked the timing of #2 cylinder and it was all over the map, most of the time greater than 10 degrees. Cylinders 3 and 4 were consistently within a degree or two of the #1 cylinder. The results are repeatable.
I have the original side distributor and the ears on the cam do look worn. I did have to do a lot of work on the advance weights to free them up but they seem to be working ok now. Is my next step a distributor rebuild/replace or is there something else I can rule out?
Thank for any ideas JB
