Default Reading Plugs? Calling all FE experts...

Hi all. Today I took ERA601 for its inaugural drive - which I will cover in general in another thread.

The main thing I would like to solve right now in this forum is a miss when under load - it starts and runs OK, but stutters and misses when the go pedal is pushed. The first thing I did was yank the plugs. Can anybody help in reading these? Are there any clues here?



The plugs are Autolite 45's, gapped to a loose .040". Are these right and gapped right?

The second thing I observed is a noticeable amount of of oil - along the base of the plug thread - see a closer up pic of the right bank plugs below.... Most plugs have it - some more than others. There is not a spec of oil anywhere else on the motor. Is this normal?



I go back to my old engine basics - 95% of all carb problems are electrical...am I in the right area?

I do not know the engine build story (it is new engine - based on the outside, a quick look under the vc's, and based on the rest of the car which has a total of 2k miles), I can't comment on much as to settings - the former owner is somewhere in the slammer, I can't call him for comments.

The car was run about 20 miles and on return to the shop I ran it up to 3k and quick-shut/killed it to shut it off - there was some run on. The plug color seems a bit white to me.

As for carburation...here is all I know....



Comments and any advice most appreciated...
