    These are from March Field. A retired mechanic there said the spark plugs were $10 each about the time when he retired in the 80's. They had to change them all the time due to fouling and (according to him) bad piloting. There were two per cylinder x28! Care to estimate the labor on THAT tuneup???

There were over 400 Super Corsair's built, don't know how many are left, 3 at least.
I was told that the Super Corsair in the first picture is still around, and flying. That it was here in Denver at an airshow the end of the summer at the Front Range Airport - static display. It's highly modified, the wings have been shortened a couple feet on each end. So it sounds as though the one in the picture was NOT the one that crashed. |

In reality however, aviation plugs are typically not changed until they are wore out. When fouled with lead/carbon, they are sandblasted then the gaps are reset. In time, as the center electrode and side electrodes erode away, a go/no go gauge that one slips over the gapped plug after servicing determines whether the plug needs to be tossed out.

I am sure you are correct, Tim. What I was hearing was from a guy who lasted worked when I was in high school. I did get the impression that they just threw the old ones away - maybe because they didn't care, or maybe it wasn't cost effective at the time.
I'm impressed, BTW, how clean you got those! So do you also work on radials?

I did not clean those...they were simply some googled pics. They are easy to clean however by first going at them with a pick to dislodge any lead deposits, then simply sand blast the ends. After that, I wire brush the threads clean, set the gaps, install new sealing washers, then coat the threads with aviation spark plug anti-sieze. I typically work on Lycoming and Continental flat 4's & 6's but at some point I will probably have to work a radial as a friend just purchased an old Waco with a round Kinner on the front.
