RE: Looking for a 23.6cc Echo?
Hi,
Check out the thread "Don't forget the Echo.." for info on this engine. The engine you want is an older 23.6cc from the mid to late '90s. They have bigger transfer ports and make more power.
Good luck with your hunting. I found mine in the junk pile of a repair shop. I've modified it, but it turns an APC 16 x 8 prop over 8000 rpm's at 4000' and 80 degrees.
