Randjack, let me butt in here. I have a large Tecumseh I got at a steal. It has a side pulley which "could" run certain generators but the rig would be belt driven. Most generators that I have seen are shaft driven. I don't think the Tecumseh would develop the RPM's to power a generator. Most generators I have seen have to run about 3650 RPMs to provide voltage in the 110-120 volt range. The voltage is in direct proportion to the RPMs of the motor. There is also the matter of adjusting it to run on 60 cycles but I am not going to wade into that. Short answer, in my opinion, unless your engine is shaft driven and you can get it up to about 3650 RPMS, it won't work as a generator motor. And then there is the matter of shaft diameter, is it tapered or straight. It will have to be compatible with the shaft hole in the generator you intend to power. And if you overcome all this, consider that the generator is going to have to be supported and aligned with the motor so you will have to make your own brackets or rubber supports or whatever to make the generator line up with the motor. Sounds like a nightmare to me. Just my opinion though. <img src="/images/graemlins/frown.gif" alt="" />
