So the problem I'm having is not in my Cougar, but in my '66 Mustang's 351 Cleveland. I really like this forum so decided to give it shot here. The problem is that it doesnt seem to run correctly if its anything above idle. It just sounds horrible with a loud possibly "knocking" noise, is the best way to describe it. Not really sure what knocking or detonation sounds like, and i have kinda of a loud exhaust already.
Little history on my engine, its a lil beefed up with a mild cam, headers to 3 inch pipes and flowmasters. Ported n polished heads, edelbrock intake, holley double pumper, Duraspark 2 and MSD 6Al Box ignition. Probably hasnt run much in the last 5 to 4 years. Only periodically turning on and moving it. Before then, it ran perfect. But since then, I've had to replace the fuel pump becuz i was getting fuel in the oil pan, but i believe it was actually a deteriorated rubber in the power valve in the carb. Since then no gas in the oil. But now running as mentioned.
So what can the issue be? I thought it was timing or vacuum advance but timing was fine when last driven around and vac advance checked out fine when i applied vacuum. I then opened my distributor and realized there was a considerable amount of corrosion on the armature, magnetic pickup, cap and rotor contacts. Can this be my problem with the poor performance and some smoking? Pictures are below. Sorry about the long post.
