I had the generator inning today for 45 minutes give or take. Got it good and warm and did some checks. The pictures are all from today.
I also turned the blower housing to the exhaust side so all the hot air goes one direction.
The one thing I noticed after it ran a while, ice formed on the intake manifold right where the carb bolts up and it tees off left and right. This one does not have the air preheater since it is dual fuel or vacuflo cooling, not sure which.
With what I saw today, I now have no problem doing whatever work is needed to this unit.
Something else I checked today, with it running and warmed up, I pulled off the crank case vent line from the intake. It still has a little vacuum on the crank case side.
So I will get the new stuff ordered for the run / stop solinoid and start doing a good cleaning inside and out. After I get it all figured out and cleaned up, I want to get the gaseous stuff to hook it up that way too.

Give him the $25. The relay and socket will cost close to $20 by the time you pay postage.

It is not worth $5 to do the work to change it over.
