The compression test was performed with the valve cover off and the throttle closed. Do u really think it makes a huge difference with wide open. Maybe small, because when starting an engine the choke is on....
I set my intake to 6/1000 and exhaust 8/1000 but I made them extra tight so they are closer to 5 and 7 and a half.I read on a karting site the intake is .005" exhaust .007", and 60 to 80 is normal on a stock engine. It will probably come up some once the rings seat. Also while doing a compression test the throttle needs to be wide open.
