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.

    Subject: Re: Oil injection?
    From: "pipercolt" <bob.pipercolt@yahoo.com>
    I have a question. On an engine with oil injection, as you add or retard the throttle aren't you adding or retarding oil in roughly the same ratio from idle to full throttle and back? If you are suppose to run 50 to 1, wont you be at about that setting regardless of throttle position? Read this topic online here: http://forums.matronics.com/viewtopic.php?p=427182#427182
