Hi Norm,
Firstly thanks for your efforts, this is a vertical shaft engine on a slasher while mine is a horizontal which is what I thought you had on your chipper as you suggested. I guess the principal is much the same but some of the bracketry is rather different.
You speak of a spring that goes over / along the governor arm and hooks between the carby butterfly and the second hole on the governor lever but looking at the photos it doesn't seem to show in the shots as it actually being there, it is on mine though. This is where the confusion lies a little between the two formats I guess.
Cheers,
BB.
