I need an 18cc--25cc engine for a project. I plan to run it on Hybrid fuel without an ignition to save weight. It's going on a semi-scale high wing kit.

I've been all over the auction site for months, but can't seam to find one cheap. They are going upwards of $40 with shipping.

I'm looking more for a $10 engine that runs. Anyone know where I might look to find one of the Featherlite weedies?
