Engine Strange Miss

    Rerouting fuel lines. Shows a restrictor valve after the connection to carb to return line is there a p/n for such a restrictor valve?
    I believe what's happening is #2 carb is getting less fuel value and is going to return line instead. I'm going to change fuel line and would like to add a restrictor valve fitting of some sort? Any part number or direction?

    There isn't a restrictor between the carbs and the fuel. The restrictor is in the re-circulation line. It is a #35 Mikuni idle jet. It isn't a .35mm orifice jet. A #35 Mikuni idle jet and a .35mm is different. You can get them at motorcycle shops, online or from a Rotax distributor.

    p.s.
    Would a .35mm orifice jet work. Seems to since some have used them. Might even be some of the fuel pressure problems some have had? I don't know and have never tested the flow through each to compare.

    Roger that is what I'm trying to figure out. I have the line from fuel pump to carbs then a fitting off that line to a fuel vent hose to firewall possibly not allowing the #2 carb to get what it needs to supply motor. This is a new plane to me and I've been trying to work this problem out. Is it possible to call you? I seen your cell number on another post.
