Premium unleaded Mogas (Shell Vortex 98 in our case) does not contain ethanol.

Thanks 0032 (& everyone else who responded). Firstly we've determined it's running rich because of the sooty plugs (& also a sooty exhaust). The fuel consumption hasn't changed - historically 14.7 lph. The engine is operating normally - no problems at idle, cruise or WOT. Most of our flying is cross country of >1 hrs at 2850 - 2900 rpm, giving a TAS of 103Kts. Re your mechanical fuel pump - you determined it was flooding at idle because revs were not constant / surging?

Our privately operated J160C (2200) has approx 610hrs over 17 years. Over the last 20hrs the engine has been running rich, as when removed the NGK spark plugs are a dense sooty black (prior to that they'd always been light tan). The only work / mods to the carby have been; in 2008 per JSB 018-1, Idle jet #35, Main jet #245 & Needle #290. In 2022 the diaphragm was replaced. Until about 20 hrs ago we used Avgas but since have changed to Shell Premium 98. The fuel level in the bowl is, as per the book, 13mm below the top of the bowl. Advice / suggestions please. Thanks, Bill

YBUY is Bunyan airfield, owned by the Canberra Gliding Club. https://nls264.wixsite.com/canberra-gliding Suggest you contact them prior for permission to land, but don't be surprised if permission is refused. Bill

Security requirements for pilots - ASIC or AVID - see below. I have an AVID only because it "ticks the box" when I do my GA BFR. https://www.casa.gov.au/operations-safety-and-travel/aviation-safety-and-security-pilots/security-requirements-pilots

I think the requirement for all licenced pilots (including students) is to have an AVID card. AFAIK the ASIC is only required for pilots who regularly fly into security controlled aerodromes. An AVID is issued by CASA, following a background security check.

Three years ago AOPA were about to tackle this issue. https://aopa.com.au/the-battle-over-asic-cards-begins/ I'm not a member of AOPA & am not aware if this is still being actively pursued.

Sorry Red - can't help with photo's. And, apart from perhaps Wikipedia, I don't know of any web pages where you can source these. Regards, Bill

I think Photo 1 is a Bocian? Photo 2 a Slingsby Dart? (Neiher of these built by Edmund Schneider). Photo 3 is an ES Nymph.

Thanks Red. The descriptive info is accurate. Several of the photo's for the ES Nymph have come up incorrectly too. But what you're doing provides a valuable data source - keep it up.

Photo's 2 & 3 are short wing Kookaburras. Photo 1 is an ES Arrow, photo 4, maybe a Grunau Baby?

How do you determine whether "the airport has Existing Use Rights under the Planning Sheme"? Thanks, Bill

Re the third place getters. They actually flew an RF-5 Sperber (https://en.wikipedia.org/wiki/Fournier_RF-5). During WW2 Werner Geisler flew with the Luftwaffe (109's?) and Dennis Mathews with the RAF (Typhoons).

I'm interested Skip. Where do I buy them in OZ? Thanks, Bill
