Granted, this is the exception, but it does exist...

Thanks John and Gilles and others. One thing about Jabiru installation perplexes me: Every Jabiru installation I have looked at over the years has had presumed cooling issues addressed with little deflectors inside the cooling cowl which is part of the engine package. This is heartening since it shows they (Jabiru) have been paying attention. The perplexing thing is: why is there no provision for inter-cylinder baffling? Every air cooled engine I've ever seen has these. (Lycoming, Continental, Franklin, de Haviland, Ranger, LOM, P&W, VW, Porsche... all except Jabiru, free air or fan cooled. Not only for cylinder and head temps, but for cooling drag reduction it is a good thing to make all the air entering the cowling do good, efficient work removing heat from the engine. Why? What am I/we missing? Jabiru installations have huge passages between cylinders and heads so a lot of air rushes through (because there's less resistance) rather than being directed through the head and cylinder finning. I also agree that the Jabiru would benefit enormously from a 6-point fuel injection system. Or perhaps 2 of the Rotec "injectors". It is really hard to evenly distribute the relatively large fuel droplets emerging from the Bing's mainjet well through the Jabiru's long, serpentine induction passages. Liquid doesn't go around corners, it sheets out on the outside of bends and crawls downstream. The major users of diaphragm (constant velocity) carbs, (Bing, Mikuni, Keihin) are motorcycles and outboards and they are mounted on a straight through manifold as close to the intake valve as practicable. Not the case on Rotax or, especially, Jabiru. Sorry for the verbosity.

Hi! Ferg. Yes it does, since the oil always drains in to the sump. Burping it gets the oil pump primed full of oil and all scavenged away to the tank and so ensures hydraulic push rods earliest oil pressure is achieved on start up. It also primes the carbs with some fuel vapour. Not withstanding .."no burp" .no oil or bust pipe or pump and that's the best time to find it !!. To prop the engine (mags off!) also gives you a distinct "feel" of any lacking cylinder compression. That's why I do mine myself. Regards and Happy New Year.

I have contacted Mr. Denis Bastein and received a reply but after promising to send the complete brake setup for the Europa within two weeks back in November, I have heard nothing since. He no longer responds to my e-mail. I would greatly appreciate assistance from anyone in Europe, especially France, in the purchase of this devise configured for the Europa. If you have to purchase it for me I can arrange for transfer of the necessary funds or allow charge to my Pay Pal account.
