Carb keeps clogging up
« on: September 29, 2019, 05:09:07 PM »
I installed a new fuel tank and sending unit because the net was falling apart and clogging my fuel line ,but my carb keeps clogging up I blow it out through the mixture screw holes and then it runs good but then it starts clogging up again , I’ve blown it at least 40 times it the last few years but it still clogs up , I’ve even tried carb cleaner and no luck I probably get a two miles of smooth driving before it starts clogging again, any input would be appreciated

Stop buying gas at stop and shop. Blowing through the idle mixture screws is not going to clean the fuel bowl. Make sure you are running a good filter. What carburetor is on it?

Remove the air horn and clean the fuel bowl and jets. There is probably gunk in there. Check your float level and drop. make sure you have a good fuel filter.
