I seem to recall a commercial mixture adjust retrofit that involved moving the main jet up and down, rather than moving the needle itself... but I could be mistaken. Mixture control using manifold vacuum is not new. The Bing altitude compensating carbs do something like that, and it was an option in the Stromberg carburetor on the A-65 in my 1941 Taylorcraft (mine just had the cover plate where it would be mounted). -Dana -- If we wish to "restore" respect for the law, a good start would be to pass only laws that people will respect. ________________________________ Message 5 _____________________________________ Time: 07:34:03 AM PST US From: "boyd" Subject: RE: Kolb-List: Re: HKS Fuel system This is good until the lighting coil in the engine quits, or a fuse blows.

Herb > Herb, I will post it when I am sure it is going to do the job. My goal is to raise the EGT from one slot rich. I flew yesterday with 3/4th of a slot rich which is 1/4 a slot richer than my coldest winter setting for the Victor 1+. The best vacuum I could pull was 4.2 inches of water, and so I could not raise the EGT to the upper limit on some of the lower cruise engine speeds. I just finished making an adapter so I can replace the altitude compensation plug in the Bing with a hose barb. This source should produce lower pressures than the inlet probe. If the weather clears up, I will try it out today. If this works, it will make it easier to convert to the system as one will not have to remove the carburetor to install the current probe. Right now I am using a junk gage and flow throttling valve. I am so encouraged that I ordered a new flow throttling valve, a vacuum gage and thin wall light tubing. At this point it looks very promising. Valve adjustment is not sensitive, and the pressure and EGT reading are holding steady. I thought of discarding the gage, but a gage costs less than a multiple turn readout scale locking dial for the valve and doesn't weigh much more. Fly Safe! Jack B.

One pilot had an engine-out and off-field landing because he adjusted the carb at altitude and forgot to readjust when he later descended. Two cycles don't tolerate lean conditions all that well. I found with them that when jetted for sea level I could fly to any altitude, including 10 to 12k without problem, though likely greater fuel burn and slightly less power at higher altitudes. My .02. Jerry Fresno ________________________________ Message 13 ____________________________________ Time: 01:45:27 PM PST US Subject: Kolb-List: Re: Mixture control for Bing From: "Tom Jones" I have the Arctic Sparrow adjustable needles in the carbs on a 503. I find that I don't make adjustments in flight any more. The reason I installed them was to richen the mid rage (3000-4800 RPM) to keep EGT within limits on descents with partial power. It does increase pilot work load and is easy to turn one the wrong way, get confused, then turn the wrong carb needle, forget which way you turned it, and end up with a rough running engine. It takes too much attention watching the EGT...it lags a few seconds behind the needle adjustment...to make sure you adjusted correctly when you should have your head up looking outside the airplane. -------- Tom Jones Classic IV 503 Rotax, 72 inch Two blade Warp Ellensburg, WA Read this topic online here: http://forums.matronics.com/viewtopic.php?p 2617#202617 ________________________________ Message 14 ____________________________________ Time: 02:38:33 PM PST US From: russ kinne Subject: Re: Kolb-List: Re: Kolb Firestat II and Sport Pilot Hi List Anyone have a BRS 1050 for sale? ________________________________ Message 15 ____________________________________ Time: 08:11:59 PM PST US From: "boyd" Subject: RE: Kolb-List: Re: HKS Fuel system > This is good until the lighting coil in the engine quits, or a fuse blows. > This still puts all the eggs in one basket...

I think you are right... but for clarity I believe the lighting and 2 cdi and also the tach coils are all on the same stator, they have separate output wires that feed their intended destinations. And you could have one coil go bad, say the left cdi... and the engine would still run on the right cdi... but if the lighting coil goes out, you are finished with charging the battery, and would be left with what power is in the battery. I do not believe there is a redundant backup to the lighting coil. My point was not that he would loose the spark if the lighting coil went out,,, only that if his only source of getting fuel to the engine was the 2 facet pumps.... and no engine driven pump. An electrical failure would quickly become an engine failure due to fuel exhaustion. If the charging circuit fails the battery should keep things going for a while,, but if a main buss fuse blows,,, even with the lighting coil working,,, no electricity to the pumps,,, no gas to the engine,,, no turning of the prop, look for a place to set it down. If my only source of fuel pumping was 2 electric pumps,,, I would want 2 batteries,, 2 fuses,, 2 switches,,, in order to have it redundant.. and maybe Dave has that under control. If not I would rethink something. Or maybe I missed something in the translation and my thoughts are all wet. I am a plumber you know. It could happen. I kind of got mostly wet this afternoon,, but that is another story.
