Ok, folks, I'm at the end of my rope. Reman Marvel Schebler I bought when I rebuilt the engine 4 or 5 years ago. Always ran great. Lately now it's very hard to start and needs the choke to run and likes to surge. Just way too lean all the time. I have excellent fuel flow ALL the time. All the screens are clean. No vacuum in the tank. All the passages are nice and clean and no corrosion or anything ugly in the carb. I've had it apart 4 times now. Even tried adjusting the float level. I have played with both adjusting screws til I wear out the screwdriver and neither will help. As soon as I push the choke in some, it stutters and the throttle plate slams shut and it dies. Choke is working as it should. My friend has a 666 also, so I borrowed his carb and it ran great. No issues at all. So, I know it's not a vacuum leak or valves or something in the engine. I also got a new carb to manifold gasket. This is my cattle feeding tractor and I would really like to fix it. Should I soak it in Holy Water?
