So whats the definition of a re-built carburetor ?
Some seem to think giving it a clean and putting a new "service kit" on, and its rebuilt !
So if you replace the air and fuel filter, change the engine oil and clean the engine on your car, you rebuilt your engine ?
All my carburetors are fully rebuilt, every part is stripped down, cleaned and inspected. Throttle shaft bushing are always replaced.
Mating surfaces are leveled to ensure airtight seal, steel parts are replated, main body is media blasted in and out.
When everything is good, its carefully reassembled.
