WALBRO carb leak.


Walbro model #275 carb. on string trimmer has fuel leaking/pouring out of carb throat. Can you help me troubleshoot the cause? If a rebuild is necessary, then where can I get the correct rebuild kit ?

Hello Ken.!

I believe you will need to rebuild the carb. There is a diaphragm that is probably busted in it. The kit should be available at any good-sized lawnmower repair shop. It is a common carb, and they should have the kit in stock.

Let us know if we can help!

Get the full kit that has the metering needle. you will need
to find the model of the carb too, like WA 225, or WT 225.
When replacing the needle, be very careful not to lose the spring
as this does not come in the kit.
