Just a tip for folks, i came up with this idea last year after discovering pattern failure with walbro LMT carburetors.

What happens is the pressed in brass inlet valve seat corrodes, and even with a new needle will not seal. Some of these seats are replaceable, some are not. But this trick works 99% of the time for me, and could save an otherwise junk carb.

What you need:
-power drill
-valve lapping compound or polishing compound
-cotton swabs

I usually replace the needle for peace of mind.

Coat the cottom swab in compound and go to town, dont press too hard. Clean thuroughly before testing, you dont want that grit in your carb.

Cool Idea...
I could see this working aswell with the clone engines with the seat in the carb. They are pressed in.
