Thanks for your response and your time.
The problem is “newish”.
When the engine starts, I would say it is a clean start although also, at times, I would say it hits hard, a very sudden start. Hope that makes some sense.
Haven’t checked the plugs yet. The airplane had its annual in June and the plugs were checked then.
I keep the log books in a safety deposit box so I haven’t checked about the mag overhaul. This airplane is generally flown about 25-40 hours a year. I doubt the 500 hour mag check is overdue.
The idle speed is 600-700 RPMs and is smooth.
Now for priming:
When the engine is cold and has sat for several days, I usually begin with 4 pumps of prime with the throttle cracked. If no response with a few revolutions, I stop and add an additional pump. If no response, I stop and add another pump until the engine starts. Usually with only one additional pump.
I have owned this airplane for 19 years and never heard the vibrator. A few years ago I had a similar starting problem and the mechanic did replace the box.
I recently installed 2 Garmin G-5s and a GFC-500. Not anxious to install the electronic ignition right now, although, the avionics don’t help much if the engine doesn’t start.
