Thread: Booster Leak

  1. #1

    Default Booster Leak

    I have a 3310 that leaks fuel out of the right primary booster. When looking down the barrel at 1800 RPM and up you can see fuel dribbling out of the right booster only. Engine seems to run fine I cleaned carb and replaced needle & seat no change not sure where to go next. Thanks.

    Can you spray some carb cleaner through the air bleeds, especially the small high speed bleed on that side please? Gary

    I sprayed carb cleaner through the air bleeds and they were open. I sprayed out the metering block as well didn't find anything plugged.

    So, what speed does the other booster start to allow emulsion to flow? If you still have no flow from the left booster, then you need to be looking at the main jet or the bottom of the main well for blockage. Gary
