When I'm in the field driving a 5' finish mower and turn to go up a slight grade, the engine has recently started to cut out (like it's starving for fuel). Initially, I thought maybe the fuel level was low in the tank and it wasn't getting picked up, but, the fuel bowl type filter is full and plenty of gas in the tank.
As a note; I had recently went through and replaced all ignition components (because of a stumble and mis-fire issue), less the coil. I didn't have this completely cutting out problem before or after the ignition work, so I don't think it's ignition related.
My engine compression is about 110 on both cylinders. Don't know what compression readings should be, but that does not seem unreasonable for a well used 8-to-1 ratio engine. It does smoke a little, which seems worse on startup when hot (probably valve guides). It does not use any significant amount of oil however.
I'm thinking of ordering a carb rebuild kit.
Does anyone have other ideas or experiences similar to this? If so, how were they resolved.
Thanks for the help !
