That is how my Mark II is built. You might be able to see a little bit of it in this video or maybe one of my other videos.

Thanks, Jack in Key West Jack in KW/Folks: Think you are missing a little history. First two place Kolb was a Twinstar. Second was the MKII Twinstar. Third was the MKIII Twinstar. There was no "mkIII classic" until The New Kolb Aircraft Company kit'd the MKIII Extra. TNK gave the MKIII the handle MKIII Classic. I fly a MKIII Twinstar, built in 1991/92, long before it was renamed by TNK. john h mkIII Titus, Alabama ________________________________ Message 4 _____________________________________ Time: 09:44:36 AM PST US Subject: RE: Kolb-List: Re: another Twinstar Mark II question From: "Lockamy, Jack CIV Atlantic Targets Marine Ops, AD.5.3.3 / Key West Det" John, That is EXACTLY the information I was hoping to gain/learn from you 'ole timers'... ;-) Makes perfect sense. All the literature I have with my 2009 Kolb Mark III Classic also has 'Twinstar' on it. Thanks for sharing your knowledge of Kolb history.

Thanks Crystal. The video shows the installation on your plane clearly. I have been wondering about the same thing as I am 6' 3" tall and at 68 years of age do not bend as easily as when I was younger. The opening in the MKIII Extra is great... especially for smaller, younger people. The hinge down the middle ruins the great view but looks like it might work better for this old codger... well old anyway. :) Bob Green MKIIIX, N830P GPAS VW with re-drive ________________________________ Message 6 _____________________________________ Time: 06:12:16 PM PST US From: "b young" Subject: Re: Kolb-List: RE: Kolb-List Digest: Split windshield... just forget the hinge.... let the plexiglass / lexan. become the hinge. if you do so, you may have to have another attach point on the side front and back to keep it in position when closed. but you would not have to look around the hinge. boyd y >>>>>>>>>>>>>>>> Thanks Crystal.

It's a Cuyuna ULII-02 on my UltraStar. Always ran great (though at the end of last season I had to replace the rear crankshaft seal which was leaking, and it again ran great after that). Last week, after flying to another airport and filling up there (with avgas), on the flight home it started behaving like it was running rich, wouldn't hold cruise rpm without sagging so I was constantly jockeying the throttle. Today, I couldn't get the proper 6500 rpm static, more like 6100, and after some extended low throttle running it wouldn't accelerate to full throttle, just wanted to quit. That's happened before if set to rich and dropping the needle one notch fixed that, but the WOT rpm is still low. EGT is also lower than it should be I dropped a jet size (one size smaller than it should be for the current air temperature) and it's a _bit_ better but still not right. Fuel consumption also seems to be up but I haven't quantified it. Avgas does tend to run a bit richer than ethanol contaminated autogas but now the tank is half avgas and half autogas and it's still running crappy. I tried running without the air filter, no change. Spark plugs look OK. I might suspect the float level but how would that change? Float needle was replaced last year with a viton needle, shouldn't be bad yet. Any ideas? -Dana ________________________________ Message 8 _____________________________________ Time: 06:51:42 PM PST US From: Charlie England Subject: Re: Kolb-List: engine woes On 05/23/2012 08:11 PM, Dana Hague wrote: > My engine is not running quite "right". > > It's a Cuyuna ULII-02 on my UltraStar.

Avgas is really nasty on plugs (and valve guides, and....etc etc). The guys flying rotaries on experimentals who run avgas have to replace plugs every 20-30 hrs. The damage can't be seen without a microscope, but the symptom a major sag in power. The thing that doesn't seem consistent (unless it really is extremely rich) is the drop in EGT. Avgas burns so much slower that it usually causes EGT to go up; it's still burning in the exhaust. Anyway, a plug swap is about as simple as you can get for troubleshooting.

I would have changed the plugs but I didn't have a feeler gage handy to gap them, and I know (from recent experience) that improperly gapped plugs can cause a 500 rpm drop. I do plan on changing the plugs next time I go out to fly, even though they probably have about 5 hours on them. Avgas doesn't actually burn slower; it's just more resistant to detonation so EGT shouldn't be affected. However, the ethanol in car gas does affect the mixture... it burns leaner, my experience is that it's worth about half a jet size. -Dana -- The city is not a concrete jungle.
