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

Did know that, apparently big difference between wide and narrow band , I’m a farmer so I’m used to throwing money away,

I’m restricted on where I can fit the sensor, do you think it would get a good enough reading in the end of the muffler, the tail pipe is to small in diameter I reckon, the other end is taken up by the turbo body

Hope so, just paid for it, I’ll keep you posted, I’ve ordered a bung as well so I can plug it off, was told they don’t like lead, mostly run 98

Yep, I do understand how that all works, had trouble once before with Leakey bowls , engine hesitation in the boost range, the enricher valve opens at full throttle to direct higher pressure into the bowls, tapped into a port closer to the turbo, fuel pressure is kept just above air box by the regulator, I have the understanding the 914 saved , spell’s it out pretty good

Yep, prop fine, 4800 rpm, map 28, haven’t got fuel flow , air speed around 90 that’s where it runs rough which I now check every time I take it up , cruise is 5400 , map 35 gives close to 120kn, runs okay, just thought a O2 sensor might show exactly what’s going on , cost $400, haven’t ordered it yet, , the YouTube video looked impressive, showed where the engine was lacking , maybe I’ll just put up with it,
