I posted a while back about not being able to keep my Champ running in the bed of my truck while underway. I'm not sure if the vent line (CA model) is plugged up or not but it now runs just fine for the 340 mile round trip by cracking open the fuel cap a bit.

With it running 6 hrs every Saturday on the way to the farmers market and back, this unit should last me how long? At what hour usage do I want to do the valve adjustment?

I think Mr. Wizard holds the record on running hours. Something like 3,000? Hopefully he will give us the right number.

I have found that an initial valve lash adjustment around 100 hours is all my units have needed. Of course, I do not have thousands of hours on them yet.

As you probably know, the exhaust valve is held open a crack while starting the engine to drop compression (easier pulling on the rope) and then as the engine picks up speed a counter weight moves the device that raises the valve out of the way. On most of my adjustments it is the exhaust valve that is off a little from break-in wear. The intake seems to stay the same.

The need for adjustment comes from wear and the stretching of the valve stem. Apparently the metals used in these engine's valves don't stretch much. CPE also uses a different rocker assembly than other GX200 engine builders that is not as subject to wear and excess valve lash.

Anyway, don't worry about them too much. Most of the time someone screws up the adjustment worse than it was before they started - unless they have experience in how to correctly adjust lash.

Us old poots like JC, The Wiz, Bill and I (only naming a few :B) grew up on solid lifter motorcycle and car engines. Valve adjustment is as natural as scratching our butts.
