Very rough idle. To the point I can"t hardly catch the carb to adjust idle screws. Not from cam profile. Cam is not that big. Engine has roughly 80 miles on it and has ran like this from the start.
1. Good leakdown test.
2. Good compression test.
3. Both above test show me that valve adjustment is good.
4. Cam is in good condition.
5. Cam was degreed when installed.
6. Initial and total timing are verified with timing light. Vacuum advance not connected at the moment and all vacuum ports plugged at carb.
7. Firing order is correct from distributor to plugs.
8. All plugs are firing.
9. Did ohm test on plug wires, all are good.
10. Tried 2 different distributor caps with same results.
11. Tried 2 different carbs with same results. Both in excellent condition. Idle adjustments turned out 1 1/2 turns.
12. Sprayed carb cleaner on top of intake runners, no change in idle.
13. I have done a check on intake gaskets and all seem to seal well. Checked any way you can think of.
14. I removed the hose from the PCV valve and the engine idled up but still idled very rough. Plugged it with my finger and it idled back down with the still rough idle.
I have oil on the backside of the valves in the intake ports. No oil in the intake manifiold. Engine does not really smoke which tells me it is not enough oil to foul the plugs and cause the rough idle. Plugs are not corroded or wet with oil. Little darker than normal though. I have a thread with this that is ongoing but this is a quick and simple breakdown of what has been checked and done. Could it be an issue with my coil or MSD 6AL box? I have a new 6al box on the shelf I could slave in.
