After I rebuilt our 302 PCM for the ski Tique I have had an issue where it loses power. If I am cruising at about 8-10 mph and put the throttle down it will momentarily lose power then take off. Quick bog then takes off. I changed the accelerator pump nozzle from the stock 21 to a 25. It appears to have fixed the issue. I also bought some different cams for the carb but haven’t tried any. Should I just leave it alone now or is there an additional benefit to going to a different accelerator cam? |

Since it appears to have fixed the issue, why mess with success?

| I was thinking that as well but wasn’t sure if there was any performance or fine tuning reason to mess with the cam. |

between cams and nozzles and different volume pump diaphragms, you could probably have enough combinations to drive yourself crazy, I think I'd just leave it alone unless you turned it into a real gas hog. Besides it's RED and Jonny likes RED
