I want to do a compression check of a 292 that I’ll have at the Stovebolt Reunion this weekend.
My brother in law who has been a foreign car mechanic his whole life says, the the old timers made sure the throttle was wide open during the test.
My question is, does it make a difference if the throttle is open or not?
I’ll have plenty of help this weekend and we will see if it does make a difference.
