Where have you got the h/l needles set,you might have to go 2 or 3 turns out on those carbs. Sometimes no matter what you do these things won't run and they are not worth the price of a new carb.

Could be the tank vent is clogged. I had a hole bunch of grief with my clogged vent once. Figured it had to be the carb so tore it apart several times to figure out why the engine would pop on choke, run for a few seconds than die.

Make sure the 4 bolts are tight that hold the back of the motor on you could have a vacuum leak. PS. Those really like a muffler mod..........

Possibilities-
Vacuum locked fuel tank, run with cap off
Fuel delivery problem - hard diaphragm, bad vacuum line
Fuel delivery problem - clogs, remove jet screws and blow out
Vacuum problem- bad carb mount, missing o-ring, bad crank seals
Clogged muffler

Normally its a blocked exhaust on those. See more of them than anything else. Only an witty bitty outlet on them.

First thing I thought of.Had one and two years in a row had a mud dauber plug up the muffler.Didn't run for crap!

Is it flooding or leaning out when it dies? Have you checked the spark?

I have a hunch its the inlet needle tip, I've seen a bunch lately where the coating on the needle tip erodes, and then flooding starts. I now pop off test every flooding carburetor.

I think that ethanol is eating the coating....

Most shops won't even work on them, I know ours won't. At $70/hr labor, they're not worth it.
