yeah, you have a two minute window to edit your posts here. by the time i noticed, it was too late 😄

Where did it get stolen from? Is there a cash converters nearby? I would ask there first...

So then, I feel I need to take the carbies off completely. If I was smarter I would have cleaned them BEFORE I put the engine in 😄 In general, and in particular with Bing carbies, what should I do? Are there other jets I should give attention to? I have a compressor there, is it safe to give every orifice I see a good enema? I guess there is a diaphragm in the top part, is compressed air likely to damage it? I'm not keen an whacky chemicals etc like carby cleaners. How far do I need to disassemble?

The following is what I've done. What else should I do? Finally started my Rotax 912 for the first time last week Ran smoothly for all of 30 seconds. Then really roughly. Then shut it off and called it a day because it was getting late. Had time to think on it, and thought maybe I hadn't tightened up all the cables and doo dads. The throttles are in the swinging arm rests so there's a lot going on (it is what it is, let's not debate what the best design is). Anyway, I adjusted everything. Hoping that it was just running unbalanced. Didn't make a difference. Next guess was a blocked jet in a carbie or something. Because I always half arse everything , I found I could loosen the carbies, and remove the bowl without having to undo the cables and hoses. At first glance the bowl looked quite clean, but when I looked closer I could see that petrol 'varnish' that can occur over time. Not heaps, but it could cause a problem I guess. So I carefully scrapped all that off and rinsed with turps. I also took out the (pilot?) jet. I couldn't tell at first if it was blocked or not. But after a bit of blowing I could see all the way through. Could have been blocked, or just fuel in there blocking the light. I poked a copper wire through to make sure. The jet in the bowl (choke? Idle?) was clearly fine and I could blow through that. Once assembled again I still had difficulty starting it. When it did start, it ran smoothly maybe be for a second or so and then roughly again. I did a few times in case something got sucked through but I'm guessing that wouldn't be likely to happen. Because in total it was enough time for the cylinders to warm a little, I noted that the right cylinders were cooler than left, which seems to me to indicate the problem is the right carbie. Oil pressure was good. Spark plugs looked ok.

I wouldnt go hard on the photographer. They would be wanting to go straight back to the couple. It was less than a second. They wouldn't have realised what they had filmed until after the accident.

Could be a culmination of dribs and drabs. Maybe more modern alloys here, shorter through bolts due to the heads being cast with the cylinder there. It all adds up. I guess it'll be shown to be good or bad once it has some hours up.

Tell ya what though. I did the oil purge today on my 912. That's when I reminisced about wet sumps 😄

I like lamp.

I like all sorts of engines, hence my original post. What I like about this engine is that it will sound like a 'big boy' engine, but not at a big boy price. I like Rotax for the most part, but some homebuilts would just sound that much better at 2500 rpm, especially replicas 🙂

Got the filter today. Made in Italy.

Goodo.

All academic now, bought a genuine one. I have no idea if I'll even keep the plane long enough to buy another filter... But for those trying to match it, it turns out the Rotax filter has an anti something valve (anti drain?) I think.

Where do I click BUY 🤔

That's the thread I started 😄. From memory no one listed a part number I can just go to Repco or whatever and order it. In regards oil hose, my mechanic sold me what he was using, not cheaply mind you but oh well. It's a blue Pirtek jobbies. This is all the info I gleaned off the hose itself. Not exactly order friendly 😄 Pirtek low pressure hi temp LPHT-08 12.7mm (1/2") 21 BAR (304 PSI) C.P MSHA 2G-1C-40C/3 101/22 FCP 12923167

I think what I've landed on, more or less is that if it goes INSIDE the engine, I won't muck around. If it's on the OUTSIDE, then it's worth investigating other sources. In this case I class the oil filter as INSIDE because it effects the oil which is 'inside'. So, while no one was able to tell me if that dealer was reputable or not, I went and bought it elsewhere. You had to contact them first to order. This is the 21st century. Click n pay, baby!

I utterly agree with you. And if someone can give me the part number right now, and show they have been using that filter for years, I'm onboard! I beg to differ about the oil hose..that seems to be inexplicably hard to pin down a basic replacement that is readily available

What skippy and I are doing though in the main is buying the same part that Rotax use, but before they slap a Rotax sticker on it. Case in point is the starter solenoid. They don't make starter solenoids.they source theirs from Denso. So you can pay I can't remember, say $250 for a 'Rotax' solenoid or about $70 for the exact same part, from the same factory. Not a knock off, but the same part. And skippy is right about the oil filter. Rotax don't make them, it will be for some other engine/s. If you can crack the code, then you can pay the automotive price for the same part and quality. Unless it's for a BMW. I'm beginning to realise if it was for a BMW it'll cost the same. Right now though I don't think anyone can tell me what the automotive OEM is for that filter. And I want it now. 😄

Most recently I bought the 90° choke cable tube from AliExpress and throttle adjuster from a go kart shop

Thats fine. Like the Opel/Vauxhall fuel pump. But if no one gives me a definitive part number, right now I'm not going to muck around with it. Remember I tracked down the Denso solenoid part number and a possible aftermarket starter motor. I'm onboard with avoiding the Ro-tax 😄

They don't supercharge quite nicely?

Yeah, even at $50 I wouldn't mind. A guy at work kept saying to me- 50 bucks! What a Rip off! But 50 bucks isn't even half a tank of fuel in my plane. And I'm happy to just burn that up 😁

V12s supercharge quite nicely 🙂

These guys do a good price. Anyone bought from them before? https://pmaviation.com.au/rotax/

Facthunter wants to buy a Rotec radial, install a supercharger and then fly to 1945 😀
