Dick, Not sure what the pressures are for the standard mains (probabily 25-30 psi) as I run 6x6.00 aircraft grade tires. I generally maintain about 25 Psi in them as you run more it may want to bounce on touch down. Much lower and you run the risk of the tire rotating on the rim and severing your tube valve-stem.Any taildragger tail wheel leads a hard life, and it's exciting if you have a failure, which should be avoided at all cost. I tend to keep both tube and tire near new, probabily replacing them after about 300 hours flying, or sooner if warranted. I always carry a spare tailwheel-tire and tube with me, which is not a lot of weight, and lives unobtrusivly under the Lightwing seat. I have had to use it a couple of times. When you buy tubes try and get the 'heavier duty' one's they are a bit thicker and a bit more puncture proof.

 

I tend to run 25-30 in my tailwheel also. And yes I have had punctures on rural properties, but don't think it is because of the high pressure. You've just got to expect one now and then, and be ready for it.

 

As a comparision, having a nose tire go flat on a training -wheel equipped aircraft can be just as inconvienent, and in the worse-case scenero can also involve prop damage requiring an engine strip-down....................................................................................................................................Maj...

Hi I've been putting 20psi in the mains and 30psi in the tailwheel for some time now. Recently I had a puncture in the tailwheel and wonder if over inflation could have contributed to it. I would be interested in what other lightwing taildragger owners have to say.

Thanks Dick

Carby problem fixed

Thanks Geoff, Ian and Ross for your helpful suggestions.I had the carby bowls cleaned at the factory and they contained fine particles of dirt as well as some watery sludge.I also replaced all fuel lines beyond the on/off taps and inserted an additional fuel filter before the gascolater.This seems to have fixed the problem as no leaks were evident after a couple of test flights.It looks like it was a dirt issue all along.

Hi I am having trouble with a leaking Bing Carby on my 80hp 912. After engine shutdown I noticed a pool of petrol on the ground and traced it to a fuel leak from the air intake side of one of the carbys.The fuel had leaked from the carby, made its way through the heater box and oozed down the firewall onto the ground.I thought I'd fixed this problem but I later detected a strong smell of fuel whilst in the air and a subsequent inspection revealed fuel had leaked onto the lower fuselage above the undercarriage.It had come from the same carby and the air intake pipe was saturated. Has anyone else had a problem like this and I'd appreciate any thoughts on how to fix it.

Cheers Richard

Thanks Ian It was just a simple wiring problem afterall. I found it fixed it and it's working perfectly.

Cheers Dick

Hi my name is Dick McCoy. I have looked through the various aircraft owned by members and noticed a few own Lightwings.I have just bought a Lightwing and I am hoping someone may be able to help me solve a problem.My aircraft is a GR 912and on shutdown one ignition refuses to cut off. I have thoroughly checked the wiring and switches and they all seem to be ok when checked with a continuity tester but when the engine is running I get no mag drop from one of the ignitions.

Can anyone suggest a way of overcoming this problem?
