problem with old Emmons Push Pull

[Joe Babb]

Working on an Emmons push pull. Not sure of its age. Is there a list of serial numbers somewhere?
I'm having trouble getting the C pedal and the E lever to balance out and in trying to get more travel in the C pedal discovered an interference between the C pedal stop screw and the little eye screw that holds the spring for the B pedal. I know these things were all built by hand one at a time so maybe that one interference shouldn't be surprising.
I can get the C pedal to work, but then the rod seems to limit the travel of the changer when engaging the E lever so it won't go low enough. Easing the rod collar on the C pedal lever then limits how much I can raise the string with the C pedal. Using .014 string. Suggestions? I've worked on push pulls before with good success. This one is fighting me.

this is a very common problem, and it is an easy fix, some guys more knowledgable will probably jump in , and help you out with that...

Fixed part of the problem. I think this one was originally set up as the Day system and I'm changing it to the Emmons system, moving the C pedal. Well, looking at what used to be the C pedal I saw that the pedal stop screw was shorter than the one on the new C pedal. Swapping them out fixed the interference issue and with more travel I'm getting the C pedal working now. Whew. Now to get the rest adjusted.
There's no separate adjustment on this guitar for the C pedal and A pedal on the 5th string. Is that normal for a push pull? (maybe showing my ignorance here, that's okay, I learn by asking dumb questions).

You need to make sure that there is enough travel for the lower to reach it's destination before you can set the raise.

Yes it's normal for 2 strings raising or lowering the same string. On the 4th string, you raise a whole and half tone, using a half tone tuner on the 3rd pedal for the E-F knee lever.
