mel,
where are you located state wise?
if you're near ct just cruise over i'll get it running for you.
things you need to check.
the flywheel may be the wrong one i had that happen a time or two
if you're not certain you have the right flywheel you need to time the motor.
which we can walk you through over the forum.
second and more likely sounding to me.
seems you have a fuel flow issue. carbs cvan run sort of when misbuilt but they won't stay running
having messed up many carb installations i have a list of likely suspects.
the motor will start and run sometimes even with the pulse hole covered.
i have a theory why but i won't cover that as it's not helpful.
first
you need to confirm the pulse hole is clear from the start to the finish .
so take out the reed block and make sure both holes are open.
second line up the reed block with the bottom of carb and confirm it lines up to carb pulse hole.
third if you have a two piece manifold make sure the second pulse hole is lining up with the pulse hole all the way to the carb.
then install gaskets being sure not to install wrong and cover the pulse hole.
now connect carb to gas line but be careful not to have any gas in the line.
in the next test we want to confirm that the carb is pumping gas.
after carb is connected to empty line roll over the engine it should then be able to draw gas from the tank to the carb.
with really good carbs it'll do this alone .
if it doesn't cover the carb with you hand preventing air from going in THIS ALWAYS SHOULD DRAW GAS.
if it doesn't theres an internal carb issue.
if it does stop as soon as the gas gets to the carb.
now watch the fuel line for air bubbles.
you shouldn't have any but a couple of tiny ones is ok
an air bubble growing or over a 1/2" long indicates an air leak.
if all this goes well try starting the engine and get back to us with results.
