    where is the restrictors?

    Drilled out restrictors with a 90 main jet in the return line to equalize fuel pressure.

    in the carb body fuel pump side. open up with an 1/8" drill. Then use a 1/4" brass hose connector and tap one side 5mm. Then screw the desired jet in it and splice this into the return to tank line.

    OsideBill: you don't happen to have pics or the restrictor drilled out and one with it not drilled out? Trying to figure out of these modified Lamey 65U carbs have them or not.

    A pic of a 44I before drilling the return restrictor out. Drill out the return with a 1/8 bit. Depending on jetting & engine setup the return line jet will vary between 80 to 110 main jet size to acheive 2/3 psi at idle & 6/7psi at wot.

    In Bills pics above the left side picture is not drilled. You can see a small hole inside the big hole. An easy way to tell is that the beginning of the hole is about 1/8" and then it necks down to a hole that's pretty small. One's that have been drilled are about 1/8" all the way.
