    Predator with tilliotson help needed.

    I have a predator 212 with .040 ARC Rod, Hemi Piston, Big Valve Head, ported, 308 Cam. With 380a tilliotson. Very strong out of the hole but when it reaches higher RPM around 7000 it turns off like a switch. Not sure if plastic fuel pump is big enough. I can turn out high speed jet no help does the same thing. If I change high speed needle to different style makes no change. Do I need a high volume pump?

    only way u need a differnent pump is if it is bad. I run a crf 450 Honda off the same pump as u have. everyone wants to blame the pump or coil when almost always something else. I know because I have done it. also everyone wants a big carb when something smaller would run better.jmo

    Running way to rich and at higher rpm it shuts off what it is doing is killing
    the spark.but if you back out of it should fire right back up.the other thing
    is were is your pop off set at ? some times you can tune with just the low
    and turn the hi off.

    Most 380a tillotson alky carbs were built for flathead engines and are too rich for ohv engines.
