You guys that are swapping new engines into your older Troy-Bilts...The Horse models use an engine with a 1" shaft....not hard to find, but different from a lot of the more common 3/4 and 7/8" shaft engines.
Just wanted to point that out for anyone contemplating a swap.
"Forget pounds and ounces, I'm figuring displacement!"
If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
