Hello. My name is Tan.

When on the water and you throttle up puch the choke. Does engine run better/ If no change squeeze the primer bulb when engine bogs. Does it run better.

If no change then we need to do a spark and compression test. The spark must jump a 7/16" gap on spark gap tester. The compression must be 90+ psi with no more than 15% difference.

Running the engine in a tank isn't the same as you can't load the engine.
