Exactly, now we are thinking along the same lines. If your 20/2 is rated to run at 1050rpm then slowing it down is just a matter of ordering a set of governer weights from the 12/2 and installing them. Then you have the flexibility to run at higher rpm's later if you like. I plan to keep an extra set of weights and an appropriate sized pulley for the generator so I can change the speed and the output if necessary. You cannot do this with a 12/2 because the flywheels are different for the slower speed. In other words, with Lister types, it is usually OK to slow one down below rated speed but not to speed one up it because the larger diameter flywheels will exceed a safe rim speed and may fail (explode)see this link to know what I am talking about

. If you look at some of the pictures of the different types of Listeroids available you will see a different flywheel on the higher speed engines than the slower ones.
The unit you describe should put out a solid continuous 4.5KW and spike much higher. It might just be all you need....and it may just last forever.
