Hi All,

Another question for the experienced mechanics out there...

What difference would you expect to see when doing a compression check on a "cold" engine versus an engine that has been warmed up?

Higher or lower values?

I did a compression check on my 2F engine during a recent tune and registered average values of about 155 across all the cylinders. This was done on a room temperature engine.

Any thoughts? :-/ :-/

Sounds like you're good on all 6. Normally I take out all the sparkplugs, prop the throttle open, choke open and give it a spin. I'd think the readings would only go up when things are warm. Even if the readings were numerically lower, be happy they're all close to the same.
