Just bought one from ebay
Not sure it has one or not till i check, the grommet is in place prob just the grommet though, so have ordered new just in case, see below. My vehicle is at my parents house some 4-5 houses down the road so cant check. chances are the valve is either missing or non existent so happy to buy new and know its ok.
repco sold me a incorrect point set, had to return and go to SCA and get the correct one. the wiring to plug into my distributor was different from the repco one provided. so new points installed but not sure how to set these in correct position ie timing. bought some fuel as well and a clear see thru hose from bunnings to see if when i crank next the fuel pump works or not (instead of relying on the starting agent).
next week with the delivery of the refurb carby + new coil = possible start for the first time if by then i can sort out the gearbox alignment. exciting days ahead, cant wait.
