So I got my new little jewel home today, and started working on it. Cylinder 1 has 0 compression. All other cylinders have 125 psi. The machine has 10,580 hours on it. It has been worked, but hardly abused. I am going to do a valve adjustment tomorrow, as I bumped the starter with my finger on the exhaust rocker through the oil cap and at no point can I feel any lash. It is my understanding I should have.012" of lash, so hopefully I just have a tight valve. Otherwise a leakdown test will come next and see where the wind is going.

Is there anything common with these motors? It appears to have been maintained, but I doubt a valve adjustment was ever done.

Also, is 10K hours excessive for one of these machines? What else should I look into before I put it in service?

And lastly, it appears to be starving for fuel at times. I get a lean backfire and lack of power, but I am not going to address this until compression is back up. Is there a fuel filter or a jet in the fuel system that could be a problem? The machine has been sitting for two years so I know it will need some love at this point, and no it is not out of propane.

Thanks again for all the help.
