Thanks much.
My linked topic shows the complete machine restoration. There is
one linked Briggs and Stratton engine that would be a good choice for these Hi Vac machines than the other linked B&S engines and all those linked Honda engines.
Most of the B&S engines and all those Honda engines all dump the exhaust at the Hi Vac chute, That one B&S engine dumps the exhaust at the opposite side. The hot exhaust might be problematic w/ the plastic chute and the nylon bag.
