10 to 1 your power valve is blown.

Paul did you check fuel bowl levels?

Interesting, those are GREAT carbs...

Just for grins, check your gas cap. Every once in a while I don't put mine on right and the fumes in the cabin get as bad or worse than an actual leak puddling on the intake...

Its going to be hard with that much exhaust duration to stop the fumes. Theres alot of unburnt fuel being drawn threw at low speeds. May want to try a wideband to see what you can do. Theres nothing like knowing your AFR instead of guessing. Where are the tail pipes?

tail pipes come out the rear

Were do you get a good wide band set up that you can use on a laptop?
