(Jeffrey Dill) ________________________________ Message 1 _____________________________________ Time: 04:55:44 AM PST US From: W Duke Subject: Re: Kitfox-List: IO240 Mine had a problem with the fuel "spider" on intitial start. Diaphragm was stuck I think. Mine had been sitting for about 5 or 6 years. Had to get it fixed before mine would even start. Also there was a service bulletin or AD on the spring in the in the spider around 3 years ago. Changed to a lighter spring thus allowing better fuel flow. Also I changed the Facet electric fuel pump to one that will run the engine in case of engine driven pump failure. The more powerful pump causes my IO240 to stumble at idle. I think it would shut it down but I have not let it go that far. I only use it for priming to start. Good luck with it you are getting closer. Keep us posted. Where are you located?

I have been building for some time, and many gave up on me, but I persisted, and am close to flying. Today's event, however, was somewhat dampened by the fact that I couldn't keep it going. It has been sitting for several years, so the factory gave me some things to do to overcome that delay. Is there anyone out there in 240 land that can give me some tips? The battery is way down, and I am charging it as we speak. I will also contact the factory to see if they have any suggestions.

Do you have an electric fuel pump for priming the system for the start sequence? You need this in order to start a fuel injected engine. If you have a fuel pressure gage, monitor it in the pre-start sequence and you should see something like 14 psi after it has run for approx 25 seconds. If it starts and dies right away, then give the pump another short hit 3-5 seconds and try again. Of course, you will have the mixture full rich when doing this. You probably have a wood prop ? They are nice and light in weight, and this reduces the flywheel effect, so it makes your engine more difficult to start and idle smoothly at the spec rate of 750rpm. If you have not done so yet, do the AD notes that change the fuel distributor regulator spring, drill the bleed hole in the throttle plate, and this will help with the idle dying on rollout tendency. Of course the idle mixture setting can only be done by trial and error, due to where it is. Learn how to lean the engine in taxi (when warm) and during normal cruise and you will enjoy very good fuel economy as well as great performance. This engine is a jewel. When you can, give us some pix of your aircraft.

From: "Jeffrey Dill" <1dillfamily@comcast.net> Thanks guys for the help. It was just like both of you said. A new bulb type primer allowed fuel to flow when not actuating the primer, just like the worn out plunger type. A replacement plunger type did the trick. Something worth noting which you guys may already know. I think the added fuel into my carburetors from the old primer caused a drop in my idle speed. That was the whole reason I opened the hood in the first place; on my first flight of the season, my idle was down well below 2000. I had turned each idle stop up one quarter turn before I noticed the gas leaking out of one carb. Today, with the plunger type new primer installed and working properly, I warmed up the engine to check the idle and, sure enough, I had to turn back the idle stops to where they were before to reduce the idle back to 2000. -------- Jeff Dill Model 2 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=300617#300617 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message kitfox-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Kitfox-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/kitfox-list Browse Digests http://www.matronics.com/digest/kitfox-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.
