I found this year after a lot of prop swinging that it actually loses its explosive capacity completely and the engine will not start. After trying all remedies to start up the 503 after the winter lay up. I drained the tank and replaced the fuel. Fired at first pull. A friend in the oil industry told me `it doesn`t keep like it used to`.

This can be done in my Mrk III by removing the between-the-wings gap seal, hooking up the gauges so that they hang down partially into the cockpit, then starting the engine (plane tied down of course) and carefully standing up, so that one foot is on each seat and your head pokes up through the center section. From there, you can make carb adjustments with the engine running and get simultaneous feedback from both the gauges and the engine sounds. A careful tap of the foot can adjust the throttle. Takes a little care, and getting your head up through the gap seal is a bit awkward, but once there, this method has worked well for me. So far, no door replacements : ) On a different thread, there has been discussion of methods to extend the instrument panel. Thats fine, but for me the only instrument I want to be able to reach is my EIS. An alternative to extending the panel is to install remote buttons for the EIS, which could be placed right below the seat. I believe Grand Rapids Technologies can set you up with this system. I personally have not yet done this, but I believe there are others that have - perhaps someone could report back with a price and their level of satisfaction regards, erich weaver ________________________________ Message 4 _____________________________________ Time: 11:29:50 AM PST US From: "J.D. Stewart" Subject: RE: Kolb-List: 912 carb balance with vacuum gauges --> Kolb-List message posted by: "J.D. Stewart" It's from this group that I first learned about the remote button leads for the EIS, even though I'm a dealer for them. I've started equipping Titans with them, since they have a similarly small panel that's difficult to reach. There is no cost from GRT when adding this option to their EIS. I wired 2 of the 3 buttons up to a G-107 stick grip, which has a total of 5 function buttons. See http://www.ultrafunairsports.com/TitanSS/panelfinished.jpg for a picture. I used the top 2 momentary buttons on the grip for the 2 left button functionss on the EIS. This gives me the ability to acknowledge the big red light if I need to, and cycle back and forth among the pages. I used the other 4 buttons for flaps and in-flight prop, along with the forward button for PTT. If you didn't have a use for those 4 buttons, a G-105 grip is the same, but doesn't have the two top bottons. You could wire 3 of the 4 buttons for full functionality of the EIS.

According to the manufacturer operating manual 87 octane is fine. Running the higher octane level increases the chance of your getting alcohol blended in as octane booster. I run 87 unless I have reason to belive the fuel may set for a while then I buy the 91/93 grade. I also use stabilizer which does make a difference if it sits in the can or the tank a while before the next flight. jerb At 09:17 PM 12/8/04 -0500, you wrote: >--> Kolb-List message posted by: HShack@aol.com > >In a message dated 12/8/2004 10:35:27 AM Eastern Standard Time, >tabberdd@hotmail.com writes: >Is it acceptable to run 89 octane fuel in a 503 or should 91+ be used? > >I [& many others] have been running 87 octane for hundreds of hours with no >problems.

Wanted to share a tip I never heard before for ALL 912S owners. This is from Eric Tucker, the Kodiak distributor rep: IF you are still fighting violent engine shake at startup (important: assuming you have the HD starter and slipper clutch already), then try the following: TURN OFF one of your Mag circuits instead of turning them both on like you usually do. Once the engine starts, THEN turn it on! This technique has apprarently been met with great success in reducing the shakes at startup. The theory is that a single mag retards the timing by just a little. When shutting down, you can reverse the procudeure (shut off one mag), then the the other. (if you are having shakes at shutdown) (I'm not referring to the shakes you might get from experiencing one of my STOL 'in the tree' landings!) This is not an official Rotax procedure, just a technique that has worked well in the field. F W I W Another 'news to me' thing is that there is a brand new carb socket introduced by Rotax a month or two ago... harder rubber composition, NOT a mandatory replacement, tho.

Last spring I fogged the engine, drained all the gas and put the plane in storage for the summer. This fall I can't get the engine to run worth a darn. Last fall it was running sweet. Now I can't get more than 4000 rpm and the engine is running rough. Last fall I was getting 6200 static at full throttle. I have tried everytning I know but can't get it to run right. Any one care to make a suggestion.

I assume that when you say "all the gas" you meant the tanks and the carb. bowl?? Have you tried new spark plugs? Does is run smooth at low rpm's and just not able to develope full power, or is it running rough? ~ Earl ________________________________ Message 12 ____________________________________ Time: 06:15:25 PM PST US From: "Dale Sellers" Subject: Kolb-List: Cuyunas --> Kolb-List message posted by: "Dale Sellers" Is there anyone on the list that is still running a Cuyuna in anything?

I have 180 hours of test time and experience that I'm happy to share with anyone else that wants to fly a VW on a Kolb. I still have a adapter mount, exhaust pipes, and Diehl accessory case that could be used to try a VW on your airplane. Make me a offer on the package and/or suggest how I might share these parts with the Kolb group. I'm app. two weeks away from having my VW powered Kolb flying again. I can't believe the number of changes caused by lowering the engine just 5 inches. Hopefully when I'm ready to fly the all the standing water will be frozen but not covered by a foot of snow here in Michigan. It's also a race to get it done before I head to Florida for the winter. I also want to beat Vamoose into the air.
