Forgive the rookie post but I'm a total rookie when it comes to Postwar stuff.
I've only got a couple freight cars, SP Caboose, a 681 Turbine, and a 2055 Hudson.
The E Unit on the 2055 seems to be giving me trouble. If the engine is on the track and I'm looking at the engineer's side, the lever sticking out of the boiler is pointed to the fireman's side. If I'm not mistaken this is the "on" position for FNR. The lever on the engineers side is for locking it into one direction.
Is there a center position?
The engine, frequently, will have fits that seem E unit related - running then immediately jerk into reverse, dropping into neutral, etc. Just tapping the lever, which is set pointed to the fireman's side, is all it takes to get it to run reliably. It seems with the lever centered, it eliminates the issues.
Is an E Unit rebuild in my future here? It is a strong running engine otherwise. My 681 is out at my Postwar/Conventional tech being totally refurbished (hope to get it back soon) and the 2055 may be going next, although I'd like to learn how to do this myself.
