Can anyone tell me the exact size of the valve lash jam nut on a Generac Model 6244 20KW. I want to make sure I order the proper size crows-foot wrench.

You'll need a shorter one depending on the model of generator.

Almost all of Generac's air cooled line uses 13mm except for the 530cc engine found in the 10kW and 11kW which uses a 10mm jam nut.

Thanks for the info Chris.

What does the old 410 use, IIRC it is somewhat larger, and I have not seen the new single engine yet.

It's still the 13mm. Looks identical to the 990's as far as valve train goes. :) I have a new one out there, but I haven't had to do valves on it yet.
