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
Just saying

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 ?
