Hi Sapper, maxwestern and NormK,
Sapper, only decompression valves with the longer stem are rebuildable. I did not know they could be run on a PT. Must be a somewhat awkward fit.
NormK, I remember you said you just stick in the first poppet valve that comes to hand with your rebuilds/modified G4 carbs.
Maxwestern, how do you tell which body goes with a certain poppet valve?
