I have over 800 hours on my 422 and other than being hard to start below 32 degrees, cured my magnetic heater and extra battery, and run-on on shut off, cured by high octane fuel. No problems.

it just hit me......you have 800+ hours on a Robin engine??? That's a lot of use in the last 2 years or so!!

That's tongue in cheek, I hope. /forums/images/graemlins/crazy.gif

John,

If your engine continues to have the same problems over and over again, the service center that you took the machine to should contact me to discuss a new cylinder head replacement. I think there could be a casting problem of the cylinder head, or possibly unexpected quick wear of the area of the rocker arm.
