Carby Rebuild

Last year I sourced a rebuild kit for the Rochester 4GC carburettor from the states and now it was time to strip the carby and put the kit through it.

Joe came up and we set to work... well... Joe set to work ;-)






All parts were soaked in thinners and blown-out with compressed air.

Dimension settings were listed in the kit.

By the end of the day, the carb was back together, sans choke linkage.

While JtC rebuilt the carb, I pulled off the water pump and replaced it with a new one sourced from Rare Spares. The bottom radiator hose was severely perished, so a new one will need to be sourced before the coolant can go back in.

Once off, the old pump had it's cover removed to reveal.... perfect! The impeller looked brand new and there was no slop in the shaft! Obviously the pump was not the reason for overheating.

So the new pump stayed on and the old pump stored away as a spare.
