  1. Maybe they're still selling 😃 then.What are you looking for? For me personally,if i'm looking out for something i put out a wanted ad, always seems to work. cheers colin
  2. We had 4 or 5 engine stoppages on approach with my early series 1 Jab at Marion field,idle was always stable on the ground.Eventually i discovered it appeared to be a design fault with the carb throttle lever arm.Throttle cable runs from left side of the engine and curves around the front then goes back to carb .My eng no high 600's later on they modified that. The carb throttle lever being alloy and the idle screw having a ball end and meeting the lever at an angle about 30 deg off from 90deg meant the lever was distorting when snapping the throttle back on approach. 2 hours with a drem
  3. I use Caltex 98 from the same dealer,and he told me it is tested every 2 weeks,i have no idea what tests they do.He also told me it's the same fuel as the Woolworths BP 98 up the road. Colin
  4. PA28 no CSP,i was flying gave a slight shudder and i noticed EGT begin to rise.Mag gear had sheared apparently,nylon?i didn't get to see that. cheers colin
  5. Hi there,no i sold to a gentleman in tewantin qld.cheers

  6. Looks like it could be doctored to me,at 0.46 left wing is just to the rear of cockpit and fin rudder suddenly is seen to forced to the right,even though the wing tip is lower than even the horizontal stabilizer.It then miraculously returns to the vertical. colin
  7. No ,but someone else is,i found the Pup a little cramped.Sold it with spare motor.They are around,in hangers,sheds.Best thing is advertise under "wanted". cheers
  8. Last time i spoke to him it was flying,a few years back. cheers
  9. I've seen aircooled engs go from heavy oil usage to negligible by fitting a good modern ring package,and my series one 3300 i would say uses too much oil,so would be interested in a set of quality rings,care to share any information? cheers colin
  10. My 230 is a 230B and i have the specific manual to suit,not sure of the difference to the 230C though,possibly throttle as mine only has the single throttle and had a basic flaw in the idle stop mechanism which could cause (and did) engine cutouts on finals.Cable runs right around front left side of engine and back to the carb.I see later model changed that. BEW 350 kg. colin
  11. So what am i missing here?fair enough speed would be up but why has fuel usage gone up at 9000ft?
  12. The colour of my chinese 4 stroke mower plugs is textbook perfect light tan,using the same fuel as the Jab.
  13. I run my 3300A on 98,after modding the ducts it ran at a too cool 245F as i realized after 30 hours plugs were always black even after repeated cleaning,did some carb tuning ended up dropping the needle and changing out the main jet temps have risen to 255F,after 2 oil changes using Camgaurd am going to W100+ as recommended here, the thing i don't get is why did Jab changed out all those cylinder heads seems like a lot of expense,when i could simply redo my ducts and end up with a motor that ran "too" cool? Ducts,cut horizontally,lifted 15 at front,30mm at rear,extended at rear i can sq
  14. Aeropup (SA) was sold to someone who started building them at Gympie,he had some fuse's build-up in his hanger when i visited. He was advertising them in USD with if i recall correctly the Camit engine included.What became of it i don't know, cheers colin
  15. I'm with you 100%,a dropped valve is my biggest concern,and i'm only new to Jabirus and that has been brought on only through reading about that issue,and through personal experience with overly hot engines testing design limits. Anyone know what uncowled radials run CHT wise,must have been pretty cool at high altitude,in minus temps. cheers colin
