The WD I just bought has a PA at the end of the engine number. I know what G and K stand for but what is P ? WD300836PA Thanks, Terry

High compression engine in WD is designated by the letters PA. Designed to burn gasoline only. KA is standard compression.

Thanks Francis, My manual said GA for gasoline but didn't mention PA. Thanks again, Terry

my WD also has PA at the end, a KA or "dual-fuel" engine would have the 45 degree exhaust manifold with the plate that can be switched out, mostly on the early WDs
