I have a 58 motor I just rebuilt.I went to test fire it yesterday. I kicked about 30 times Not a bark or pop. This is a brand new motor thru out. excellent fire & compression, but not getting ANY fuel. The trick I use is, remove the plug, add about a half a straw of 80/90w oil,install the plug turn the motor over a few times, remove the plug, install a straw's worth of fuel into the hole, reinstall plug. Motor fired right up, BY HAND. ALL these motors need to be primed when that are new or have set for a while. This motor fires up by hand every time ya press the kicker. Just saying ----- ORIGINAL MESSAGE FOLLOWS ----- my mechanic and a few of you brought up the only test to take . a compression . since the gas is drawn in to the intake by suction { no accelarator pump } if the suction is low it will not get gas to pump thru the carb . some one mentioned putting a plastic bag over intake , right ! only i will use an auto cylinder pressure gauge screwed into the cylinder , i am told anything less than 110 lbs won't pull gas to the engine . when i asked how a new engine only three 3yrs old with 20 miles on it has low psi he said the ring froze / rusted to the piston .and i am loosing compression. that happened from not turning the engine over . well thats it i got work to do . sorry about hogging up all the space , will stay off for awhile ., will be looking for comments ..........what cylinder psi should i have ?
