Hi David,
That back up nut on the backside will loosen it up if you can get at it. As an
alternative you can cut the rubber boot off and grab the outside metal with a
pair of vice grips or something similar. Sounds like it is no good anyway so
tearing it up shouldn't be a problem.
Regarding different switches, one may have been replaced in the past or have a
different amperage rating than the other.
Best,
Carl

I spent some time yesterday replacing the original engine panel (Universal
M4-30) buttons/switches and ran into a problem. I had bought a new Cole Hersee
key switch and two push button switches for the replacement. I was able to
replace the key switch and the glow plug button easily (only a small amount of
blood and pain). However, I realized that the original push button start
switch is different from the glow plug button. The glow plug button has a
rubber hood that can be easily removed and a knurled round collar nut on the
outside and another nut on the inside to secure it. The start button has a
rubber hood that appears not designed to be removed and a rounded collar piece
with no knurling that secures it on the outside. I have been unable to remove
that collar and it is not clear if it is threaded. The inside nut is different
as well, and it is so tightly spaced to the body that I have not found a tool
thin enough to get to it and loosen it. Anyone have suggestions on:
1. Why these two push button switches are different when the presumably
perform the same type of function?2. A flat tool that can get to a narrow space
for a large nut (something like a bicycle pedal wrench but adjustable)?
3. How that start push button switch is supposed to come apart?
