It's time to clean carburetors, recently i bought couple more carburetors so i can piece together couple good carburetors, first thing i did was to power wash all of them with high strength degreaser to take the grime off but the carburetors are extremely dirty inside and out. the plan is to make one good vacuum secondaries also one more mechanical secondaries carburetor, i pick the best carburetor and spent close to 4 hour taking it apart and cleaning it i did manage to get it spotless, blow out all the passages and run wire thru them, then i started assembly, i made all new gaskets from klingerit gasket material, and follow the factory service manual and assemble it, this took surprisingly long time, and now i have to learn how to tune a carburetor, i'll be installing a lambda sensor in the exhaust to run Air/Fuel ratio gauge so i can get it close then tune it by spark plugs.
