Ok, i looked at the wires mentioned but not sure what to do here. I was able to disconnect two of them the other two have to be cut to be disconnected, which I didn't do.
here's a pic of the wires. I disconnected the yellow one which I assume is the oil sensor, was also able to disconnect the top black one in the pic. the other two cant be disconnected . not sure what any of these wires is for.

By the way, RSCurtis, you mentioned you have a copy of the service manual for this machine, I would really love to get a copy if possible. Honda doesn't produce or make them available anymore and the only one available are for the newer models.

Mine is a hard copy- I found it on ebay. From your photo, disconnect the white wire if it goes into the flywheel area. If so, it should be the ground for the coil. If you have spark with it disconnected, the coil is vindicated.

My manual shows the coil ground as a black wire that passes through the top of the block behind the flywheel. It's not clear from your picture where the white wire goes. Failing that, if you disconnect all the wires that are plugged you should isolate the coil.

That little silver box on the yellow wire might be a time delay which overrides the low oil cut off during starting.

One of my portables has that built into the Run/Off switch.

I'm not sure how Honda does it, but that may be it.

Folks,
My EM6500SX has an automatic choke. In very cold weather (less than 30F or so) it will start then die when the automatic choke releases, and then refuse to start again for an hour. Pulling out the manual choke to restart didn't help and perhaps made things worse.
The solution for when it is very cold is to give it some manual choke when firing it up. You will hear the automatic choke kick out and from there you have to keep it running with the manual choke for 60 seconds. You have to adjust the choke to keep it running but around 1/2 choke seems about right at the beginning. Just stay with it for at least 60 seconds. Then ease the choke off. This has been a reliable method right on down to 0F.
