    Soot on spark plugs

    Problem solved! Thank you all for your comments and suggestions! It seemed like an induction leak was most probable, so I took another look. I pulled the Number 3 induction tube and the gasket came off in pieces. It was stained and very brittle. I can't say for sure that part of it was...

    Soot on spark plugs

    For the past 19 years I am the single owner/flyer of a 1963 Piper Cherokee 180, with a Lycoming O-360-A3A. TTSN on the engine is 2699, 241 since SMOH, and 20 hours since annual and oil change. I lean aggressively during taxi, and use my JPI EDM930 to lean to peak EGT while I cruise at 2400-2450...

    Winter oil weight

    I've been using xc20w50 for years. When I had my engine overhauled, the shop commended the use of this oil. Plus I don't have to give it a second though when the weather changes.

    63 Cherokee 180 overhead lights

    The S/N is 28-1399. I'll take another look, but was previously unable to locate a resistor. Do you think the resistor would be adjacent to the switch or perhaps closer to the bulb?

    63 Cherokee 180 overhead lights

    Hello, I am new to this forum and hoping you can help me with an electrical challenge on my Cherokee. The overhead instrument light and nav lights are controlled by a DPDT toggle switch that can set the instrument light dim or bright. The dim setting no longer works. I have verified that both...
