I'm not sure why Rotax has mechanical synching after pneumatic. I do it the other way, that's how it's spec'd for the 912 and my HKS.This is really so simple, it just seems intimidating until you do it once. As with all things done with a running engine, tie the plane down and have an assistant ready to hit mag switch(es) if required. Before you start raise throttle cable boots so you can get at the cable adjustment screw. Give each cable a tug to see how much slop there is. When you get to cable adjustment that's most likely the one that will have to be adjusted. 1. Adjust idle air screw per Rotax or Bing for your engine / carb combo. 2. Warm up engine to operating temperature 3. Hook up manometer (incidentally, someone on the list suggested two stroke oil instead of water, I used transmission fluid because I had it loaded into a pressure gun to fill the brake system on my trike. That is the easiest way to get the fluid into the tube. Using oil also makes the levels a little slower acting so you make an adjustment and wait a bit for the fluid column to react. It's also less likely to get sucked into the engine if one carb is severely out of synch to the other. To get the initial level set before you hook up to the primer port blow into the tube with the higher level until they're even. 4. Start engine and let idle. Screw in idle adjustment screw on carb connected to the fluid column with the lower level until the columns are even. If that makes your idle speed too high adjust each screw back out until you get the idle speed you want and both fluid columns are even. If you do have to back out an idle adjustment screw make sure you haven't brought the throttle cable up tight so that the carb piston is no longer setting on the adjustment screw. 5. Set RPM to 3000. Loosen adjustment screw on the top of the carb with the lower fluid column and screw out adjustment until columns are almost even and tighten lock nut (this will raise the column very slightly, which is why you don't want to get them exactly equal. It's not much but you are after perfection, after all). 6. Shut off engine, disconnect manometer lines and plug with an AN 3 screw so the manometer stays clean, replace primer plugs or lines. I did my 582 while I had the wings off as spinning props make me nervous. I put an eyebolt (my local surplus store sells them cheap) in the board so I could safety wire the manometer to the aircraft, you could just as easily drill a hole and run safety wire through it. That's it.

I would not want much less power than I have though. The 80 HP Rotax 912 is pretty cheap used, and would be a much better engine for the MK III Xtra than the HKS for this plane. I think the MK III would be ok, but not great with 80 HP. I think the MK III Xtra would be HORRIBLE with the HKS. I think climb would be so poor with the HKS that it would be dangerous. This is just a guess as I have never flown an extra with that little power... I do know what my MK III Xtra climbs like if I run just over half power, and it hardly qualifies as a climb.

The weight of my Firestar is pretty close to what most of the lighter Mark III weigh. The wings on the 3 are larger so it would fly, but I wouldn't want to own one. Larry > --- Reading this thread persuaded me to go back and dig out my April 1995 copy of General Aviation News and Flyer, which had a full article on the MKIII with the 503 and 582. In the article, the 503 is described as "perfectly adequate." (I can scan the article and post pictures of it if anybody cares) I got a chance to fly a dual carb 503 powered MKIII with a passenger on board & full fuel. This was a bare bones airplane, no electrical system, maybe just a strobe, it weighed (supposedly) 475 pounds. It was really pretty much a dog, and it was a cool morning. So IMO, although the HKS makes more power than a 503, but less than a 582, unless I lived in flat Midwest country, probably the HKS engine on a MKIII is not a happy choice.

Richard Pike MKIII N420P (420ldPoops) Even though the HKS makes more power than the 503, I find that it is offset by the additional weight. I can fly faster with the HKS, but I cannot get off the ground as quick. The only plus is the "apparent" safety factor of the four stroke, and the longer TBO. Larry ________________________________ Message 16 ____________________________________ Time: 09:17:46 PM PST US Subject: Re: Kolb-List: Re: HKS-700 on a Mark III or extra From: Richard Girard Well for what it's worth Richard, the original J-3 Cub started life with a Continental A-40 engine of 37 hp and weighed 2/3 more than a Mk III. I was flying my neighbor's Taylorcraft last week with an A-65 Continental and it too weighs about 2/3 more than my Mk III. Flew real nice. My Mk III will out climb the T craft but he blows by me (relatively speaking) over 15 mph faster at slightly less fuel burn than my 582 can deliver. It's all relative.
