Yeah, there are several Holleys that have 850cfm....some are race carbs....others are street carbs....some have chokes, some don't....I was just checking to see what all would be adjustable on yours.

All the things you're naming are pretty valid. However, I don't think plug gap would hurt you that bad. Also, if a plug was bad, the engine would be missing. It could be fouled however, and just needs a good dose of high-performance driving.

You can check the plugs on that side and see what they look like. That will give us a good starting point to see what's going on.
