Call Jim Gorumbie at Western Hobbies (602) 647-0165 and look at the Evo 26cc. I have seen these and actually held one on the ground....A stump puller.....see at www.westernhobbies.com ....Ask Jens about this too.......Jim Gorumbie is a top notch guy and treats a person good.....Tell him King and Woody From El Centro sent you........What engine would you put in this? It calls out for a 20cc gas engine, but I was thinking 26 or 28cc should be fine. Zenoah has one with electronic ignition, but so does 3w? any ideas out there?
