Motorized mongoose beast powered by poulan

[Dan shaw]

I've got several projects going right now, my favorite of these is my beloved fatbike who I've put together several good ideation so back and forth do I take it e bike or gas until finally while in Home Depot I saw the solution on sale in the form of a cheap poulan chainsaw 42 cc. $139 a bargain and turns out a perfect fit. Next is replace the crankset with a dual freewheel

Interesting to see if it works out...
Chainsaw motor

Motor should be fine but I'd go with a clutch assembly. No way I'd go direct drive on the crank even with a freewheel.

You can use a freewheel crank, which I think is what is planned...

Just thought I would mention that the chainsaw motor does have a centrifugal clutch.
The first motorized bike I rode had a McCullough
chainsaw motor on it with a crank sprocket mounted/welded to the rear hub...scary fast, bad brakes and loud as heck....."Oh to be young and bold again" !

Thea's I'm trying to engineer my freewheeling dual sprocket crank to fit this weird ... bottom bracket on the beast
