(Frank Fanelli) ________________________________ Message 1 _____________________________________ Time: 05:50:09 AM PST US Subject: Kolb-List: Re: Oil injection? From: JC Gilpin To clarify, I really like the oil injection as well, but would add another item of maintenance, after my last experience with the broken oil line. Any such plastic/nylon/rubber lines carrying oil or fuel and exposed to the weather need to be replaced regularly, even if they still look OK.

From: Larry Cottrell Thanks to all of you for your insights and information. Like most things, simple is better and as close to foolproof as possible. As with most things however maintenence is the main solution.

Those of us that have flown the Kolbs a bit forget what it is like to fly other aircraft.

I bet your were off the ground in under 200 feet. Is that a 912 100 hp? Frank, thanks for sharing your experiences and how you shoot approaches. -------- Wesley Elliott Sport Pilot-PPC Read this topic online here: http://forums.matronics.com/viewtopic.php?p=427031#427031 = Photoshare, and much much more: = = = ________________________________ Message 4 _____________________________________ Time: 03:13:00 PM PST US Subject: Kolb-List: Re: Oil injection? From: "alienwes" For every failure of oil injection there is probably a failure of the pilot to remember to add oil when pre-mixing. -------- Wesley Elliott Sport Pilot-PPC Read this topic online here: http://forums.matronics.com/viewtopic.php?p=427090#427090 ________________________________ Message 5 _____________________________________ Time: 04:37:43 PM PST US Subject: Re: Kolb-List: RE: to inject or not to inject...

My only experience with oil injection was years ago on 2-stroke motorcycles .. I loved it. I used far less oil, I kept my hands clean when fueling, the engine carboned up less. I am interested in using it on my 447 or 503. OPTIONAL (off-topic): Years ago I bought a Rototiller at a yard sale. Huge heavy thing, self-propelled, gear box, built like they usta build. Cast iron, etc. It ha d a big single cyl engine under a cowling in front. So, I used the thing a fe w times, it ran great, it was quite a machine. After a while I figgered I'd check the valve lash, change the oil, etc. Tore into it, to my surprise it was a 2-stroke! Yeah, I know, makes me sound dumb. But it ran so slow and had such torque. So after a few hours of operation I finally started giving it oil in the gas. No apparent damage. ________________________________ Message 6 _____________________________________ Time: 06:06:43 PM PST US From: Frank Fanelli Subject: Re: Kolb-List: RE: to inject or not to inject... Hi everyone: This subject of oil injection is pretty timely since I'm on the verge of installing an injection unit on a Rotax 503 DCDI. It seems to be pretty straightforward but there is also a problem. I use prime instead of manual choke on the 503 to get it started and the prime line goes to the nipple on each intake manifold. That seems to be the same place where the oil lines have to go also. Can anyone suggest a workaround? Would a tee fitting work? Does the manifold need another nipple? Thanks for any help anyone can give.
