Default Re: Bicycle Engine

We used to use vertical shaft briggs horizontally. The biggest hassle is the big cast in mount. We had one minibike with a big flat plate that allowed them to bolt up easily. We used a regular oil slinger from the vertical shaft engine and a homemade manifold with various carbs. (usually from a Honda xr-75)
The engine doesn't care how it's mounted as long as it gets what it needs and doesn't fall off.
The 3.5hp briggs flatties revved their little brains out vertically and took an amazing amount of teenage male speed abuse. Cheap and numerous were the advantages back then. Horizontal shaft motors cost more back in my childhood when everyone had a minibike or gokart. Verticals were boat anchors.
If more is better, then too much is just enough.
If you can't afford it, build it yourself.
