Think about getting rid of fuel filters and putting in fuel/water separators instead. That is in addition to rebuilding the carb(s).

What are you doing with the choke while it’s running? What are you doing with the throttles?

I always use throttle to start the engine.

Partial choke can be used to diagnose a lean condition. If part choke makes the engine run better then it’s lean for some reason.

Just to be clear and for future reference... cranking is when you have the key turned to start and the motor turns over. If the starter is not turning, you’re not cranking.

Good luck. They are simple engines, but not very domesticated at idle.
