Blueprint 347 with Holly sniper. have done many.... proably too many....starts and just idle to show off the sound. I am now at the go-kart stage and when i put it in gear it wants to stall, il drive a hundred yards give a little punch and engine will stall. A lot of exhaust smell.... I am thinking it is running too rich. Also now does not start imidiately as it did in the beginning. I just installed NEW identical plugs and verified the gap.

Whats everyones thoughts? before i call Holly.
