    these are smartcarb brand carbys. they are claiming fuel economy and emissions equal to fuel injected 2 strokes. supposed to be getting great results on 582 rotax. their main clientele are dirtbike racers. what i would like to know is if they save up to 30 percent fuel how does it effect the lubrication of a 2 stroke. fuel injected 2 strokes like the etec outboard pump oil directly to the crank and cylinders. these carbs have no jetting either.

    A bit aggressive Skippy. Did you get up on the wrong side of the sonex today

    You have quite often remarked on Rotax being badly designed and having all sorts of faults which just don't happen in the real world. It's extremely rare for you to post a positive comment about Rotax nev. I would agree with you if there were broken 912s everywhere but there isn't. You can buy a 2000 hour flight school engine and run it trouble free for years in a private aircraft. mark said they don't do any balancing but to me it just says there engineering is excellent which even you admitted earlier.

    Another Curtis valve. Genuine Curtis brand

    I replaced my Curtis valve. Not cheap at $54 but now it's always dry under the plane. Used to be greeted by a big wet patch on the floor each weekend. Didn't like that when av gas is $2.80 p/l

    It's pretty rare for efi to give much trouble these days. In saying that, if you seen the Birdsnest of wiring and crap on my hks engine you would never put it on an aircraft.

    An engineer from Kenworth told me the Datsun 1600 was a BMW copy and they were a better car. He was from Kenworth though not Datsun. On the highway between sale and Stratford is an old garage. Local rumour is that the owner was the original importer of datsun and he made his fortune off royaltys

    912is does away with all this drama

    where can i look up your information. i have never heard of the 180b being a merc copy. i know the datsun 1600 was copied off a bmw and a lot of people say it was better than the bmw. ford bought into mazda when the rotary nearly broke them

    He only needed a tooth count. I know the 700e and 700t use different ratios but he may be able to supply a drive gear and driven gear in 700 e ratio anyway. Otherwise I can flog it off for parts. It's only something to play with.

    Waiting on the agent in America to get back to me. He is going to see if he has the gear. Being a turbo there are quite a few differences to the na version which he has everything for.

    never seen so much wiring for a small engine, weighs a few kilos on its own.

    tryed to turn over the hks today and it was locked solid. seems it came out of a wreck i thought i better pull the gearbox and have a look. its not too healthy. broken reduction gear. interesting thing is it has a slipper clutch, didn't save the gear though.

    who cares that you could make a 1920s car backfire. i used to have respect for you but not after the shit you said about me earlier. accusing me of being on here with different names.
  18. BrendAn
    please stick to aircraft or find a car forum

    people say its dangerous for 9 series rotax to have carbys mounted on top of the engine yet when do you ever hear of any catching fire. about as often as you hear about them back firing.

    heard of the memphis belle. i will call the xair the taco bell

    there are lots of 618s around, still a lot flying now. i thought you worked on most aircraft engines. they have 2 different carbys. good for 1000 hrs plus flown by the book . crankshaft breakage probably happened with cold siezure, not a common problem.

    For the Rotax 618 UL, the main jets typically differ between the PTO and MAG carburetors, with common stock settings being #135 (PTO) and #145 (MAG), though these can change with altitude, intake silencers, or specific setups, with larger jets (like #160/#170) often needed at lower altitudes or with silencers to prevent running too lean, a common issue for this engine. Key Jetting Information Standard/Altitude > 5000ft: #135 (PTO) & #145 (MAG). Sea Level/With Silencer: #160 (PTO) & #170 (MAG). Why Different Sizes? The 618 uses two different carburetors, and they require different fuel flows for optimal performance,
  23. BrendAn
    Surprised you haven't heard of that before. It's well known . My egts both run around 600
  24. BrendAn
    My 618 had the intake silencer box removed. They had to rejet the carbs to allow for the change in restriction. Interesting thing with 618 is the main jets are a different size in each carb.

    Any filter can block up. That's called maintenance. When you change or wash them at required intervals.
