Greetings,
This 4 stroke J15R4SNF idles roughly and just gurgles when throttle is applied. When I first got it no water was pissing so we Replaced the water pump, fuel pump, plugs. Mikuni carb I cleaned really well cause the rebuild kit is on back order. Air/fuel adjustment screw has little effect.
Compression tested both cylinders and they are both registering 50 psi. Maybe this cheap $30 tester is way off but this seems awfully low. The last owner was a young kid now I wonder if maybe he overheated the motor and blew the head gasket or worse.
