Just a side issue here - as I said this motor was aquired because I was after the special double pulley attached to it. This pulley with its spacers measures 82.4mm high. The PTO on the B&S is 80.3mm long. The PTO on the new Honda GXV390 comeing next week is 79.5mm long (according to specs)

Will there be any problem bolting the pulley and spacer straight on the Honda - no hassles with pre-load or anything? Should linish the spacer down so total height of the pulley matches the length of the Honda PTO?
