I'd just like to remind everyone that when replying to an email hit 'reply
to all' because if you don't no one on the list will see your reply.
Here's my reply; Those compression numbers do not seem too bad. Do
you have any idea how many miles on the car since it was rebuilt or if it
was ever rebuilt? I would next do a leakdown test and that will tell you
more exactly where you need to look. If you can't borrow a leakdown tester
from a friend I think the big chain auto parts stores rent them? You will
need an air compressor also.

$Thanks for all the input, it was very helpful, I didn't know that the
$throttle needed to wide open, but that make sense. So I ran another
$test.

$Battery fully charged, throttle blocked wide open, valves adjusted,
$engine warmed up. I use 10w40 and a bottle of motor honey. It smokes the
$worst on startup, blue smoke, also smokes at idle but clear up when
$revved up. Number 2 & 3 sparkplugs look ok but # 1 & 4 are black with
$carbon. If I wanted to change out the valve seals, does that require any
$special tool? Pull the cam, rockers, and springs? Probably needs a full
$rebuild though.

$Thanks, Owen.
