Well I modified my distributor today and put the 64 jets back in and returned it to my base settings. I regained control of my idle and it performs extremely well again with the exception that the surge it back/still there. I ordered a set of 66s today that I will install tomorrow, it will be too rich I believe but I can at least see if it solves the surge and go from there.

I ran out of time so I haven't changed a plug to the 64s like Mr. Cab suggested but I did buy them and there in the front seat, no difference noticed so far. I will do that after I see what the jets do and will up date as I go with pictures of the a plug before and after.

looks like carbon buildup in that plug, you have a choke on that carb? any black smoke out the exhaust? can you see raw fuel dripping in carb when at idle?

Thank you. Yes a choke, no noticeable black smoke but I little eye burn from rich idle, not bad but you are aware of it in a closed area and I really haven't looked down the throttle of carbs since the Cuda is so frickin wide and only 5'7" or so and I'm not wanting to climb ontnhe fender.

make sure choke is fully open when warmed up, try another carb if you got one.

I am gonna post pictures of 6 different plugs under different driving conditions, all are with 66 jets and 34* total timing. All are Autolies AP64s or AP65s.

64s with about 10 miles of "normal" driving some in town, some open road at cruising speed.

65s 10 miles "normal" driving.

64s 1/4 mile WOT, let off the gas, cut it off and costed into my road, changed the plugs side the road.

65s 1/4 mile WOT, same thing.

64s 50-60 miles of "normal" driving, some in town, some open road cruise speed.

65s 50-60 miles of "normal" driving, some in town, some open road cruise speed.

Let the analysis begin, I have my opinions but will hold them for now.

Mr. Cab, I would really appreciate your thoughts.

Ok I am gonna post 6 different plugs, all of them are Autolites either AP64s or AP65 in different driving scenarios.

64 with about 10 miles of "normal" driving including some town and some open road.

65s 50-60 miles of "normal" driving, some in town, some open road cruise speed.

Let the analysis begin, I have my opinions but will hold them for now.

Mr. Cab, I would really appreciate your thoughts.

Thanks, Kevin
