In your last post you said you cruise 4800- 5200 rpms. That is about where my EGTS start getting too hot. I believe you said you were running a 11 G 2 jet needle. One last question.

It was about 6200 rpm until I alter the prop tips to make it quieter ( earlier discussion). As far a EGT temps, I have the old service manual from Rotax which gives specific numbers for EGT's and CHT's. You may already have this information, but if not, here it is. It states the upper limit values as such: CHT at spark plug seat - 450 F difference between two cylinders - 36 F EGT - 1200 F difference between two cylinders 45 F As I stated before, I run EGT's from 1075 to 1190 depending, sometimes pushing 1225 at higher altitudes. From what you wrote before on 2-10-08, I think your worrying about nothing. I would like to see what would happen in your were able to borrow another EGT gauge and see what goes. Also, our senders are not always accurate. I had a problem with wiring connectors last year messing up my readings. Another test that would be interesting would be to borrow another carburetor and see what happens. Did that for a friend and what a surprise. Someone else mentioned looking for an air leak. Might want to spray WD 40 around the carb mounting rubber and manifold while running. Blue smoke will let you know if you have one. As my friend and 2 cycle Guru keeps telling me, over and over again, look at your plugs and cylinder tops and you can tell whats going on. He tells me not to chase the gauges. Of course you have to learn what to look for! Also, if you take off your exhaust Y once a year you can observe what's happening in there and if your rings are free. Yes, I'm using the 11G2 needle, but that is for mid range performance and I don't think it will solve your problem. Got that idea from the list years ago! Can't remember the gentleman's name, sorry! I may have to change again when the Ethanol "monster" strikes here!!!!

I take that to indicate a lean condition! I think my gauges are somewhat accurate. When the egt gauge reads 1200+ the engine starts running rough. When I pull out the enrichener the engine smoothes out and the egts drop. When the weather clears I am going to put back the stock jets and put in a little more pitch. It will be warm weather here before long and that will make things a little richer also. I did a de -carbon at 50 hrs and now have 78 hours on it! Ed **************Ideas to please picky eaters.

From: "grantr" After a long wait I finally got to fly my mark III today. What a nice flying airplane! Its amazing how much different it is in yaw stability vs a challenger II. My instructor helped me get a lot of little things checked and fixed before flying. I got down there to his airport (2.25 hour drive) at 10 am and we finally finished a little after 4pm. He flew it at 4:30 to give it an initial check and by 5:30 I took my 1st flight in it with him! The 503 performed very well just as good as his challenger. The Kolb will cruise nicely at 50 to 55mph at 5 to 5500 rpms.. Indicated stall speed seems a bit higher than i though it would be. Empty weight on the plane is 425# + me 150+ instructor 165+ fuel 60= 800# gross Indicated power off stall was around 43 mph clean no flaps. Does that sound about right? temp today was about 75 degrees elevation 185 MSL Solo stall speed was about 41mph with a gross of about 700#. The plane has to have at least 195# in the seat to be within the W/B. What kind of indicated stall speed are you all getting? All in all I had a great time! I really like the Kolb! Landing is a tad tricky with the tail wheel but takeoffs are very easy.

Grant I will give you the same advice that Travis at TNK gave me when I was bending gear legs with great regularity. Learn to wheel land it like a sail plane and you'll find it's the sweetest landing airplane, tailwheel or no. Once you get that down you can start learning to three point it if you want, but you really should learn the wheel landing first. Just my opinion, but I have the hydraulic press time straightening landing gear legs to back it up. ;-) Rick On Feb 16, 2008 10:08 PM, grantr wrote: > > After a long wait I finally got to fly my mark III today.

From: "JetPilot" Grant, Your experience with the higher stall speeds is normal. Adding VG's to your Kolb will get that stall speed down to where you want it. I had close to the same stall speeds with my MK III Xtra, which is much heavier than yours, and putting VG's on it made a new airplane out of it, not just in stall speed, but the way it felt throughout the lower speed range. Below is a shot of my panel during slow, right on the edge of stall, level flight. I put about 140 VG's on my wings, from the center right out to the very tips of the wings. Its critical to install them very precisely, but if you do you will be well rewarded. Mike -------- "NO FEAR" - If you have no fear you did not go as fast as you could have !!!
