Default 94 Marathon Cutting Out At Full throttle

Hi
I just purchased a 94 Marathon as a rescue project. I replaced the batteries and when I floor the accelerator pedal it cuts out. When I let off the pedal a little it runs abot 11-12 mph with no problem. Is there an easy way an easy way to adjust the throttle linkage on the marathon to avoid it cutting out?

Thanks for your help!

Sounds like the Pot-Box throttle is going over 7000 Ohms, which the controller interprets an open potentiometer and shuts down.

I've never seen one, so I don't know if it is easy or not, but here are a couple things that might help you figure out how to adjust it.

Thanks! I will take a look.

Do you adjust the screw in the picture?

Has anyone adjusted this before?

I've had this problem and adjusted the pot box as described above. Use the search function and there are s few threads that give u a step by step on how to adjust with use of a multimeter. Pretty simple and I haven't had a problem with it cutting out ever since
