However, briggs v-twins i found are around $800-900 USD, as the Predator on HF's website is $999.99...
I'm not knocking predators as they seem to do very decent considering the price point and parts can be found for the smaller horizontals, but not sure about the 22HP's, you can probably get a new carb, spark plug and coil, but are you going to be able find any internal parts? what if a head gasket blows? or a Governor gear lets go, or a camshaft goes bad? then you may have to spend another $800-1000 on replacing an engine just because you can't find one part.
I know for a 100% you can get the briggs parts.
