Can anybody tell me what the points gap and timing should be for a SACHS SA290, single cylinder engine. My sled is in need of a tune up and I had to replace some of the original ignition parts.

Thanks

The fact that you are looking for tune up info on a 71 Sachs is testament to what a great little engine the single cyl. Sachs were. I've owned 3.

Point gap: .014-.018
Timing is measured in inches and is .157-.177 BTDC. To do it per specs you'll need to mount a dial indicator above your piston.
