Don't know what's going on with the Spezio/O290? I've noticed an occasional "popping" sound, like someone lightly tapping on maybe the exhaust pipe(or something else) with a ball peen hammer, while taxing in for some time. Only a few times in a minute or two...... Today it was constant after leveling off in cruise. Seemed slightly worse when leaned. I turned around and went back, total flight only 5 minutes.
Back round. Haven't managed to fly much, maybe a half hour once a week just to get the oil temp 180+ for 10-15 min. This flight only got oil up to 150F. I did a compression check and wasn't surprised they were only 64, 74, 64 and 7o/80. Was expecting one would be worse...... One mag. was missing slightly too, will check that out. I came home, hurting, sweating and riding bike wanted to get home before the sun went down, hate cold in my old age.
Any ideas? Got me spooked, WILL cure it! Might be the mag? I admit since I've only flown it 10-15 hours/year while flying the AD2, I haven't had the mags off in a couple years....they are coming off(bitch w/9" mount) AD2 mount had me spoiled. Oh well
Thanks,
Jack
