I started losing power with a commensurate decrease in exhaust gas and cylinder head temperatures. Then I started experiencing "hiccups". It turned out to be the filter. It looked perfectly clean, but the oil had congealed to where it was severely restricting the air flow, and I was running more than rich. Try cleaning and re-oiling your air filter. It might make your problem go away. Please let us know what you do find: it may make it easier for one of us to solve a similar problem in the future.

A lot of people have remarked that it may be carb ice. I don't think it is because I get an RPM increase even sittting on the ground at full throttle when I pull the carb heat half on. This is in Florida in 85 degree temperatures and relatively low humidity for this area. The engine also immediately picks up RPM when the heat is pulled and immediately looses it when it is pushed back in. Now maybe there is some problem with this carb not atomizing the fuel well unless it is heated a little. If that is the case I would suspect that someone else would have seen this problem in the past. I do plan on ordering an EGT to be sure the mixture is correct and see if it changes when the carb heat is pulled. I will probably also order a mixture indicator from [1]http://www.halmeter.com/. This uses an O2 sensor in the exhaust. I also will be adding a MAP gauge and may even try a temporary Radio Shack temp probe in the carb while on the ground to see what kind of temps I have. -----Original Message----- From: Harold Woods Sent: Oct 21, 2003 4:31 PM To: Brian Kraut Subject: rough engine. Hi Brian Sounds to me like a classic case of carb ice. It may be Florida and 85F on the ground which gives you a high humidity. Go up to 8500 feet and the temperature is much lower but the air still has the same weight of water vapour in it. As it is pulled through the carb the temperature falls further, the water condences and freezes. You get carb ice. Add enough hot air to melt it and keep it from reforming, adjust the mixture to suit and you have solved the problem. Regards Harold Woods Orillia,ON.Can.

I have an 1835 VW engine in my "KR Construction Trainer", aka "Flying Squirrel", and the oil drain plug leaks. I know there's a way to keep the drain plug on VWs from leaking, the usual attempt to fix this results in a stripped hole by overtightening the plug. Besides using a new drain plug gasket every time, what is the 'secret'? Latest update on my Squirrel is cowling construction, at http://www.flysquirrel.net/cowling/cowling.html for anyone who cares to take a peek. Thanks!

Thanks Wayne ----- Original Message ----- From: Brian Kraut To: Sent: Monday, October 20, 2003 2:59 PM Subject: KR>strange engine problem > I have a real strange engine problem and I was hoping someone could possibly shed some light on it for me. I have a VW2180 with a Zenith carb. The induction system for the carb has a round hole in the cowl that is about an inch and a half diameter. Behind that is a rectangular airbox that has a K&N filter element that is about 4 X 7". That goes into a piece of 2 1/2" SCAT tubing into the carb heat box which is mounted to the front of the carb. There are some pictures at www.engalt.com/kr2.htm > > My engine has been running pretty smooth except for a fraction of a > second stumble about every thirty second to a minute. During a cross country last week at 8,500' it would give me the little stumble about every fifteen seconds after I was flying for a few hours. It isn't a stumble that would make you land, but one that you pay attention to. I have a cockpit mixture adjustment and had it out about an inch during cruise. The engine would run rough and loose power at two inches out, and it would still give the stumble and decrease RPM if it was pushed in any more so the best I could tell without an EGT is that I had the mixture adjusted correctly. The oil temp is fine and the CHT was only about 280 degrees. > > Just for grins I tried pulling the carb heat in case there was some > icing even though there was no visible moisture and I was in Florida on an 85 degree day. I noticed that when it was all the way on I got the normal decrease in RPM, but when it was about half way on the engine smoothed out, picked up 100 RPM, and ran perfectly. > > My first thought is that maybee I had the mixture lean because the > mixture richens a bit when carb heat is on, but with the carb heat off I got a definite RPM decrease if I pushed the mixture in more and it didn't make the engine run any smoother. Another thought is that I was getting a lot of ram air pressure which was leaning the mixture, but again, that doesn't explain the fact that the engine runs best at altitude with the mixture pulled back some. I thought that maybe I had to much resistance through the filter and opening the carb heat some gave me more air, but that would have made it richer and leaning it more would have made the engine run smooth, which it didn't. > > Mark had a post a while ago about someone who had a ram air system > that didn't port the float bowl air vent to the same pressure that is at the front of the carb and I possibly have the same problem, but I don't think that I am getting that much ram pressure with the filter and I have the same symptoms on the ground or in very slow flight when I have almost no ram pressure. > > Any one have any clue what this could be? > > > > _______________________________________________ > see KRnet list details at http://www.krnet.org/instructions.html > ------------------------------ Date: Wed, 22 Oct 2003 10:11:18 -0500 (CDT) From: To: Subject: KR>VW Engine Rockers Message-ID: <1093.66.196.7.14.1066835478.squirrel@www.vvm.com> Content-Type: text/plain; charset=iso-8859-1 MIME-Version: 1.0 Content-Transfer-Encoding: 8bit Precedence: list Message: 8 Hi All! I'm doing a top averhaul on my Revmastr 2100. I ordered new head and pistons etc... My question, when I took the thing apart there were shims under the rockers. What is the proper way to shim the rockers? Are they there just so you can get the proper valve adjustment screw engagement? or should I just put it togeather and see how the valves adjust, then shim if I have a problem?
