R7268 re-birth

I am trying to fire up a Lawn-Boy R7268 that my neighbor gave me that sat for a long time. I cleaned all the mouse nests out of it, cleaned the exhaust, ignition and carb. I replaced the spark plug and fuel line and it looks new. When I try to start it, it will fire up with a gas spray down the spark plug hole and will continue to run if I keep priming it. When I stop pumping the primer it dies. I see in the manual the carb has an altitude adjustment but I don't see it. I believe the issue is in the carb but I did mess with the gap on the fly wheel. The motor has about 80 psi compression but it leaks down Any advice
Thanks
