How many hrs on your engine
-
Worst cylinder was no 2, left front, could definitely hear bubbling in the oil tank, so I reckon the valves are good, 70/80 , the bore scope sounds a good idea but I’m not sure I’d know what I would be looking at, wonder if just a set of rings would make a difference, read that the bores hardly wear, hard as a cats head, found on eBay a full set of pistons and cylinders only 95hrs, $1200 plus freight from the US could be a scam but might be worth the gamble.
-
Would it be possible to replace the pistons and rings and maybe valve guides give the old cylinders a hone and go again, I reckon the bottom end looks solid, could be a cheap way out although I have out jewed myself in the past with mixed results
-
Only private flying, having trouble trying to justify over $50K on a replacement so I guess I keep up the service and hope for the best, worked okay so far , Wally tells me plenty have well over 3000 up
-
Over 1900 hrs on my engine, no 2 always felt a bit soft in compression when flipping over the prop, leak down showed 70/80 , rest about 75/80 , going past the rings , should this be a concern or just keep flying, engine doesn’t use any more oil than usual

Thanks

Maybe end up going through the week

Hi anyone flown the VFR track through Nowra , I’ll be heading south, wondering if it’s easy enough, Greg

At around 4500 revs my engine definitely has increased vibration ,below 4000 and above 5000 it’s good , I think I come across this in another thread, it’s fitted with a O2 sensor so I know the mixture is correct, prop been balanced, could this be harmonics , has anyone else come across this

Noticed a soft compression one one cylinder so ran through a leak down test sat the gauge on 80 , three read 77psi but the sick one was down to 75 psi , I guess not a lot of difference, could hear a faint bubble in the oil tank , engine has 1850 hrs up, would a set of rings an a hone fix this , back in my 2 stroke days rebored to get everything round , engine is a 914

Dumb question, but how do you access the track logs from the skyecho
-
If there is a DPDT switch could that be the problem, not easy to get to the trim motor
-
Sorry should have said it’s on the elevator, I’ve got manual flaps
-
Trouble is the thing only stops working in the air, would be better if it didn’t work at all, it has 5 wires, I think 3 are for the indicator
-
Having intermittent problem with my up trim , down works always but up stops now and then, don’t think it’s in the switch, pulled apart and looks ok, can sometimes get it to work if I touch the down trim , not sure how to the thing is wired, looked up a wiring diagram and looks like it earths out back at the switch but I can’t figure out how it reverses the polarity , would there be another relay or controller to do that, there is a birds nest of wiring behind the panel so not easy to trace
-
Okay, you’ve talked me out of it, thanks
-
It took a few rinses to get rid of the frothy water, the plastic looks as solid as my other petrol containers
-
Okay, they had roundup or glyphosate in them , probably just as corrosive as petrol maybe
-
Can anyone see a problem using plastic 20 lt ag chemical containers to store petrol in , have got plenty to choose from
-
Have replaced the throttle cables with good quality ones, smooth operation, carby balance looks good, at 5000 revs the butterflies would be nearly fully open , engine revs to redline on takeoff, has a inflight adjustable, if I run it at 5300 it’s good but when I pull it back to 5000 it’s very noticeable , I thought if the prop was out it would vibrate through the whole range, I’ll get it checked anyway
-
Noticed Engine vibes between 4500 and 5000 , above and below, all good, Carbys just done , gearbox recently done, could it be prop balance
-
If you let your RAA membership lapse for a number of years do you have to go through all the training to be able to start flying again , son has lost interest but hopefully take it up again some time in the future
-
I ended up welding the plug at the start of the tail pipe where it leaves the muffler , leaves about 300mm to the end hopefully will get a good enough reading,
-
Money is a bit of an object more so when I got charged $400 for the floats
-
Understand, but I have a 914 , that’s not about to change, I do like to fly it and have the engine run sweet if that means doing a bit of tinkering I’m more than happy to do that, not sure why all the capitals
