What a thread for my first post...
Most recent ones come to memory-
Taking off on a 1500' grass strip in a stripped down super cruiser (is there such a thing as a NICE banner plane?), field is cut out of the trees, and boardered by marsh, creeks, swamp and trees. At about 150', the engine starts missing and backfiring, but doesn't quit outright, surging, and not putting out much power though. Can't turn back, and nothing but swamp to land in, playing with the throttle, mags, carb heat, you name it. Finally got it started back up at about 20' while getting ready to flare.
Turns out one mag was firing at 23 degrees, the other at 33... hmm, no wonder it wasn't running right.
Few months later, under tow on the beach, noticing that I've been slowly adding throttle for the past couple of minutes to hold altitude. Decide to try and get home now while I can. Engine is starting to run real rough now, throttle's wide open and I'm at 400, losing 50 fpm.
Now I'm just trying to find a place to dump the brand new panel I was towing where we could recover it later. Looking around, I'm over the Atlantic Ocean, nope, we'll never see it again. The beach is out, I'd kill somebody in the process. Don't have enough altitidue to cut across the barrier island and dump it in the intercoastal waterway. Just pulled a 180, and hope I can get to the southern end of the island, clear the bridge, and dump it in the brown water.
Make the decision if I go below 100' I'm dumping the banner nomatter where I am. Trying to troubleshoot now; tried switching mags, no dice, left just about quit, same with right. Carb heat? Lost about 600 RPM, started coughing and backfiring, puffs of black smoke coming out of the stacks. Waited a few seconds, only got worse, wasn't carb ice.
Mixture? It seemed like it almost quit from being over-rich with carb heat... I cleared the bridge by about 50'. Engine slowly smoothed out with a leaner mixture, but the CHT's were WAY up there... started to pull power back now, I've got a gentle climb.
Made it home OK, all 4 bottem plugs were lead fouled, and the #4 was dripping with oil.
Cleaned the plugs, was back in the air in an hour. Started to lose power under tow again, was able to catch it earlier though, slight roughness. All that ran through my mind, not, "OH $H!T" but, "not again!"
Landed ok, pulled the jug, the piston pin had slipped somehow, and hand been rubbing against the cylinder wall. The end cap was gone, found after a brief search in the oil sump and screen, along with most of the compression and oil scavenging rings...
Plane was back in service in 2 days... <sigh>
