what brand generator head? do you have a web link?

Well, I can buy a new 22kw generator head for 650.00 or a 15 kw for
450.00. I can actually buy a complete, running car (for the motor) for
100.00 from a friend which is cheaper than an air cooled motor.

I'm not worried about the fuel economy since I'll only run it once in
a while for perhaps 8 hours.

I figure I can buy the parts and assemble a 22kw generator unit for
1000.00 or a 15 kw generator for 800.00. I'd rather have the larger
unit.
