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,

Carbys just repaired by wal , floods, everything replaced, not sure how accurate the egts are don’t have carby heat, I guess because of the turbo although it has a intercooler fitted, previous owner, feels like it’s rich around those revs , winding some pitch on the prop makes it run a bit better

Going to have a go at installing a O2 sensor, seen it done on a 912 , YouTube, still not running like it should , good idea or not ?

Is there a way to recalibrate the the lights on the display for the elevator trim it bottoms out with 3 bars left blank and overruns ot the top of the gauge, hope this makes sense

All that and no difference, did notice at 5000 revs when I done a mag check the engine didn’t like it , both the same , pulled the plugs and were all very black , swapped them with new ones about to try again and thought maybe check the air filter which is mounted in the bottom cowl , easy to overlook, caked solid and beyond cleaning as it would fall to bits, after much driving found found a good enough replacement at the fendt dealer , fingers crossed will fly again tonight, looks like I may overthought the problem again.

Found the needle clip out on one carby, right hand carby should run one notch lower to make it a bit richer something to do with the boost favoring the side, they were both the same, but noticed when I advance the throttle one side gets ahead of the other , they both finish against the stops , not sure what’s going on , have set them up with a carb mate not easy with the spinning prop , bit hot and windy to test maybe later

Okay, I’ll have to pick up my act, rather than write a novel I thought I would keep it to the point

Rough running engine between 4800/5200 , new throttle cables , Carbys done, balance good , runs fine either side of those revs,

I’m starting to wish I hadn’t asked the question

I just took it off , looks like it wasn’t worth the trouble, thanks for all the input

Agreed, but I noticed when waiting to enter the active runway and checking for incoming aircraft the ones with their landing lights on seem to stand out more

Ok thanks I’ll get onto it

Just fitted a led to my landing leg, super bright, been a couple of midair’s so I figured it might help on final, trouble is it drowns out the radio , any way I can make it work, wired it to the nav lights

Trying to figure out what the idle gear on the starter shaft drives in a 912 , I think I understand how the sprag clutch works

Wondering where I stand legally

Wondering what’s involved in flying with a engine that has passed TBO, 914 engine in my plane has got 200 hours left , compression hasn’t changed , no more oil consumption, have flown it from 400 hrs to nearly 1800 , $45000.00 to replace it

Maybe just leave the hinge exposed

Thinking of taping up the gaps in front of the ailerons, is it worth doing and what tape would be best, I thought it might kill a bit of drag which I read somewhere
