There is a letter after that 26105. I need that letter.

Last number is ***** the generator itself not paperwork
Customer reply replied 6 months ago
That should be an N for first letter
Technician: Hank F., Technician replied 6 months ago

OK - that is what I needed.

The first thing you need to do, if it has not been done already, is give it a good tune up. Change the oil and oil filter, air filter, and spark plugs. Make sure to get the proper plug, and gap them to .025".

If that doesn't help the starting issue, the choke may need to be adjusted.

Start the genset, and let it run until it shuts down - to the point that it will not restart.

Then check both plugs to see if you are getting spark.

If not, we need to look at the ignition system.

If you are getting spark, loosen the fuel line at the carburetor, and crank the engine.

Is fuel flowing?

Maintenance was done. If we move the throttle linkage to governor and hold it it will run smoothly but we can't always hold it. Is there a way to adjust?
Customer reply replied 6 months ago
I think we have fixed it ourselves! My husband did something to the governor linkage. It is now running fine.
Technician: Hank F., Technician replied 6 months ago

ON that model, it is common for the clip holding the governor rod to come loose. If that is what happened, replace the clip, as it has become worn.
