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.

Fact of the week
Foundling hatches are safe, anonymous drop-off points for unwanted infants, allowing parents in crisis a way to surrender a baby safely without fear of punishment, ensuring the child is rescued and cared for. The concept started in the 12th century, was abandoned in the late 19th century, then reintroduced in 1952. It has since been adopted in many countries.
