Every idea I received gave me something to consider. Here is where it's at today: After running up to 1500 RPM. I used a can of starting fluid and sprayed every nook and cranny. Pretty much every where except in the carb inlets (ok just a little to see what would happen)(It bogged). I heard no change at all other than that. When I wasn't spraying I was watching CHT's and EGT's. CHT's could not get warm enough to even get into the green. EGT's could barely get in the green if I ran up to 2000 RPM and let it go for awhile. Sounds like a very rich condition yes??? Now for a little back ground: I bought this airplane from a couple of good ol' boys in St. Joe, MO. (That is a story in itself). Now mind you I have nothing against good ol' boys from St. Joe......... When I got I home and got down to details. I found a lot of things not acceptable to me. I have never heard it run or saw it fly. Normally a red flag but I got it so cheap I couldn't pass it up. My wife would argue but I still think it was worth it. Any way enough rambling. Both carbs have main jets = 158, Idler jet = 45, Needle jet = 2.7, Jet needle = 1K2. The top ring of the needle has the O-ring and the clip right under it on the second ring. The air screw is at .5. The floats arms are level when the carbs are upside down. I believe I have the recommended 1/2 inch of space between the top of the float bowl and the gas level in the bowl. Altitude at Stevens Point, WI (5 miles away) is 1050 ASL. The three finger test mentioned in my last post still has me scratching my head. It tells me that the carbs are still different in some way. Is a K&N air filter considered a "silencer"? Thanks every one, Ray W.

They always have some celebrity on it throwing candy and trinkets out the back, and the kids at each stop are waiting to catch the goodies - sort of an Appalachian Madi Gras... this year it was Wynonna Judd as the resident celebrity. Here are some pictures I got of the train in Fort Blackmore, VA. about 20 miles north of here, another one coming through a tunnel, and one crossing the big trestle just north of Clinch Mountain.

Does any one know of a source. It would be nice to know things like bolt torque specs and pattern, plug gap, acceptable cylinder compression etc. I did a compression check and got 115 front and back. The plug gap should be ok because the plugs are brand new. The prop is bolted on and is providing a suitable load. All fuel lines are brand new including the impulse line for the fuel pump. The impulse line is 6 inches long and was ordered from LEAF specifically for this purpose. The entire fuel system is brand new this airplane did not even have a fuel tank when I bought it. It is an older engine with points ignition. Thanks every one!!

Read through this thread for additional ideas: http://forums.matronics.com/viewtopic.php?t=62699&highlight I believe you have to take the 2-stroke Rotax class to get the repair manual. All the other manuals (installation, operators, maintenance) can be downloaded from http://www.rotax-owner.com/ under "support>engine manuals". -------- Cristal Waters Kolb Mark II Twinstar Rotax 503 DCSI Read this topic online here: http://forums.matronics.com/viewtopic.php?p=274178#274178 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message kolb-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Kolb-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/kolb-list Browse Digests http://www.matronics.com/digest/kolb-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
