I'm having a heck of a time getting an MPC 8250 diesel running. It acts like it is binding up. If you press down on it with a decent amount of force it runs fine. The gears on the truck and armature look good. I can usually solve problems with these motors by putting a 1/32 ball bearing into the plastic hole the armature sits in in the truck but no luck this time. Is it possible the posts the 2 small gears are on are worn out on the truck and causing it to bind? Any ideas? If not anyone have a good power truck for sale for this engine? Thanks for any help!
