After fiddling with my Bing Carb with two tuning kits (needles) and various inlet designs to get my EGTs to even out, I could never get my idle to run smooth under 900 rpm (I have the Jab 2200 serial #852 with 180 hours). I finally drilled out the idle air inlet per the JSB and now after fiddling with idle jets and idle adjustments, I can't get a decent idle under 950 RPM. I don't recommend it.

It works fine.

While I think this is a long shot, it only takes a few minutes to try and would eliminate it from the possible problem list: Block up your air intake port on the cowl and then remove the air-intake tubing from the carb so it draws air from inside the cowl and then finally try starting cold. If it works, then you have an air intake system issue. As they say, it is either fuel, air, or spark :) Don Read this topic online here: http://forums.matronics.com/viewtopic.php?p=240933#240933 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message jabiruengine-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/JabiruEngine-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/jabiruengine-list Browse Digests http://www.matronics.com/digest/jabiruengine-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.
