REFLECTOR: Severely rough-running Franklin

[Dave Philipsen]

You can check this by doing a pressure check on the cylinders.  If you 
have a leaky cylinder and you can hear the air coming out through the 
exhaust pipe, it's probably a sticky valve.  On a Lycoming, you can see 
the offending valve stem by removing the exhaust pipes and looking in 
through the exhaust port.

Sometimes a sticky valve will unstick itself after the engine has warmed 
up.  Then it starts running smooth again after maybe 5-10 minutes.
