Engine Misfire Saga - Update

[Terry Stapley]

Last evening after receiving all of the great suggestions from forum members I went to the garage and dove in!! I:

Checked that the plug wires were indeed in the correct firing order - check

Checked Dist. cap again for anything abnormal - raised the spring steel contact a bit just to make sure of contact - check

As per suggestion I removed the alternator belt - check

Used Carb Cleaner again on the air bleeds - the idle air bleeds(Toward the outside ?) were clear on both the primary and secondary sides - The high speed air bleeds (Center two ?) on the secondary side were clear but the primary air bleeds kept blowing back carb cleaner so I perservered and finally got those two clear

Checked the plugs on the two offending cylinders and they were a little dark but not wet - check

I did the MSD instructed spark check for the 6AL box - good spark - check

I then fired the engine and it ran fine but was idleing a lot faster then it used to so I lowered the idle with the idle adjust screw - I let it warm a bit and shut if off to put the alternator belt back on - Fired it again and again it ran fine - All header pipes were hot enough to flash water sprayed and the RICH exhaust smell was gone (Wife was happy with this)

I did all of this in about an hour and 15 minutes as I had another commitment
and I will fire it again this evening to see how it runs, but as for now it seems okay!

I really have no clue as to what the issue was as I changed more than one thing at a time because of the time constraint but the idle speed being different leads me to believe that the carb was the culprit.

Thanks for all of the suggestion!! You guys are the best!!
