Generator keeps running

[Tincup]

A friend of mine has a Generac generator in her MH. When she turns off her generator it keeps on running (Diesels)for a few minutes. It's a gas unit, she has changed the oil, filter and performed all routine maintnenace but no help.

Is this a timing issue or fuel related? What could cause this? Any help is appreciated.

I had the same problem with my Generic (see sig.) when it was new from the factory. I also found that the factory was useless to get information from.

I finally checked the intake/exhaust valve clearance. Can't remember for sure what it was but it was in the .030-.040 (thirty to forty thousandths) range. That was WAY to much! No wonder it was hard starting, loud, lacked power and ran on when shut off. A friend who works in the small engine field recommended that I adjust both the intake and exhaust valves to the .004-.006 (four to six thousandths) range.

Viola! Now it starts better, doesn't run on, but it still has lousy voltage/frequency (low power) control, OH WELL never again!
