THE STAHLE PERFORMANCE INC DIFFERENCE: QUALITY: There is a major difference in the quality of a carburetor rebuild by those who simply install a gasket kit and those who RECONDITION a carburetor. We go beyond rebuilding by reconditioning parts to or above original holley factory specs.
POWER VALVE PROTECTION is another added feature that is STANDARD in EVERY carburetor we rebuild. All new Holley carbs come with power valve protection from the factory, however older Holley carburetors did not. We install a power valve blowout protection check valve on ALL carburetors we rebuild. This prevents power valve failure in case of backfire. Most rebuilders do not take the time to install this simple kit. We do because it is critical for preventing premature power valve failures.
REBUILD PROCESS: We disassemble and soak every carburetor in NAPA MAC professional carb cleaner. This removes all varnishes and deposits that may have accumulated in the carburetor passages and ports. All main bodies and metering blocks are blown clean with 150 psi compressed air. All carburetors are througly inspected for defects or worn/broken parts. Our carbs are GUARANTEED not to have mechanical defects such as stripped threads, cracked baseplates, worn throttle shafts, etc. All carburetors are hand assembled. We install jets, pump nozzles, power valves, and metering plates sizes as specified in the Holley Carburetor Factory Specifications Book. All carburetor floats are leak tested prior to install. Our throttle shafts are hand checked for play to ensure we meet acceptable tolerance limits. We will machine throttle shaft bores to fit bushings and ream brass bushings to original size only as required for out-of tolerance units, restoring the carb to original performance specifications.
