so... i rebuilt the aisan carb on my rt52 coupe and am having nothing but trouble getting it to run right. no matter how i adjust the float it just overfills the bowl. should i keep screwing with it or ditch it in favor of something else? any imput is greatly appreciated. the weather is nice now and im dying to cruise this thing:(

Sounds like the needle is not seating. Fuel pump pressure too high? Needle does not have the rubber cone or rubber cone is dried out? Floats not floating? Crud on the needle seat?

make sure your float doesnt have a tiny hole in it. fuel inside float = no float = always flooded.
My rebuild sheet for my carb came with a specific way to adjust the float bowl. Did you get one of these, and did you follow it?

Check your accelerator pump nozzle it could be blocked.
