SELLING John Deere (Efco) CS56

[Nutball]

I never got around to modding it any more after sitting apart on the bench for a year. I put a carb kit in it just now. It's going to the MMWS GTG to see if it runs. It ran before the carb kit, but poorly.

Plenty of room for more porting. The squish & base haven't been cut. Very thick cylinder walls. I think it's a 46mm bore. Ports are around 98,116,81

Piston and cylinder look good, apart from my beginner port work. This was one of the first I ported. Just smoothed out some rough casting bumps and added shallow bridge ports.

I got it running. I had to plug the priming line to the carb. It used to run well with the old primer bulb broken, but apparently not any more.

My ear says it was revving up around 14,000 and was cutting around 11,700.




Yep, sure enough in the video it is cutting around 11,800 in the 13"x15" pine, in general between 10,400 and 12,400:
