Posting about a friend’s Continental C90-12F that has a cold #2 cylinder.
Engine recently overhauled, however on the engine runs the number 2 cylinder never gets warm.
Items that have been checked and rechecked;
· Mag timing, both internal and to the engine
· All of the ignition leads to the right cylinders
· Compression checked
· Spark plugs check to make sure they make spark and at the right time. Put all of the plugs on the leads and rotated the engine starting with the #1 cyl to verify that all plugs fired in the correct sequence (firing order 1-3-2-4) for the l/h rotating mags.
· Jug was pulled and inspected along with the lifters
· Intake runner and exhaust checked for blockage
I suggested that he check the internal timing via a procedure in a Lycoming guide, even though the other 3 cylinders seem to be playing well. Even though written for a Lycoming, should still work on a Continental. (see page 94 in this link http://www.joespiper.com/Lycoming.pdf)
Puzzled since all of the component to make fire are there and at the right sequence, but still no luck.
Has anyone else seen symptoms similar to this?
