Did a carb set up to cope with my brand new Stage 3 hybrid turbo yesterday with my LM1 wide band got it idleing great ticking over nice with high 13. drove it all afternoon having a play. Went to start it today and it ran like a bag of ****e with very rich fumes and a bit smoky from exhaust. can anyone point me in the right direction or is there anyone close to derby that can help me set up my 5. My engine has 285 piper cam set up as a cup mod with a rejetted carb 1.2 main 1mm a/c 1.2 second stage.
