I am looking at a set of EZ-Start 570G cams. Since they lift the exhaust valve a little during cranking, how do you get an accurate compression test ?

Couple of options. Loosen the exhaust pushrods or pull a spark plug and briefly run it on one cylinder. Then do the same for the other cylinder.

Good answers right there. It's also a good idea to get the numbers when the build is fresh so when
you go to compare them later on, you have a baseline to work from.
Don't forget to block the throttle open too (if you're doing the Ex pushrod option)

Sounds good. I thought about loosening the exh pushrod, but wanted some verification. Never thought about running on one cylinder.
Thanks for the input.
