|
|
just for information.... on my way home from the rock house to Utah,,,, when I descended into Buhl Idaho for fuel, my 912 started running a bit rough. it was not continuous just a split second of rough then smooth right out. but it repeated itself every few seconds. after refueling I did a run up, every seemed to run smooth. so I thought that I maybe had had a bit of carb ice... I took off with the thought of returning if all did not sound or feel right... the 912 purred like always.... until I reached altitude and throttled back. this time the vibration had only short periods of smooth between long rough periods. I tried the enrichener, but that made it much worse.... tried turning off both mags one at a time.... the mags made no difference.... went back to WOT and things smoothed out... by this time I looked out the window and was over another airport, chopped power and landed.... The kid at the airport was just putting away his RV7 and was going home.... he hung around long enough till I got things running smoothly again..... I checked the float bowls, all looked good, no debris or water. then I noticed the float bowl vent tube, I have always had it vented into the air cleaners.... but on one side the tube had kinked. I asked for a bit of safety wire, straightened out the tube wrapped the kink with the wire, put it back on,,, The wire kept the tube from folding over,,, I went for a high speed taxi text, then did a loop around the pattern.... everything ran smooth... so I departed for home, a 2 hour flight without problems.
moral of the story,,,, keep the float bowl vent lines open...

Hi Boyd,
Glad you figured out the problem and made it home safely. And thanks for posting this - one more thing to be sure to check out during mt pre-flights.
