This past weekend I picked up a 8305 steamer at a yard sale, I believe this is from the early 80s or late 70s. Not 100% but may have come in the Milwaukee rd passenger set. The shell looks very similar to a postwar 2037. Anyway When applying power the engine runs perfect forward but in reverse it only hums and vibrates. I opened the engine and it has a 2 position e unit which is in fact cycling. Seams like the motor is fighting itself in reverse, I was thinking maybe ts a DC motor but then I don't think I would have it running so well in forward. Any ideas what I should be looking at next? I don't believe its a e unit issue because it would most likely just be silent when in the reverse position rather it is vibrating like mentioned.
