Justin,

The first thing I would suggest is to see if the choke coil is OK.1. Remove the
choke unit from the engine.

The coil is mounted on top of the choke.

Look closely where the electrical wire (terminal) attaches to the choke. That is
actually a brass plate and you should see a small wire running from the plate into
the coil.

If the wire is intact take a wire wheel or emery cloth and shine up the the top of
the coil.

You need to see if there is continuity between the center pole in the top of the
coil and the terminal. If you have continuity the coil is good and you should be
able to make the choke work.

Next see if there is continuity between the terminal and the choke base.

I ended up drilling a small hole in the center pole of the coil about 3/8 of an
inch deep, threading it and attaching a ground cable to the frame of the
generator. Be sure to use a ground strap that is not insulated as the heat will
melt plastic.

I actually went all the way into my coil only to discover it was not necessary.
The choke is grounded through the center pole on top of the coil, then to the
mounting brackets. If there is any corrosion or crud between the center pole and
the coil cover you loose the ground and the choke won't work.

If you don't have a continuity meter you can use a pair of jumpers hooked to a
battery and just see if you can can actuate it.

If none of the above works let me know and I'll do my best to explain how to get
inside the coil to look for broken wires or an open circuit.

Best of luck
