Built Predator 224

[SunDevil1]

I have a Predator 224 flattop piston, billet rod, hot 275 cam, 28lb springs, champion rockers, billet flywheel. VM22 carb with 150 jet at full throttle it seems to need more fuel and the bowl runs dry. do I need to raise the gas tank or install a pump? Coleman ct200u-ex

You need to buy a genuine vm22-133 and the smaller needle and seat to use a pulse pump. you can hack a China one i think by lowering the float a bunch or running a return setup to the tank. But I’m not sure how well that actually works.

You have provided no data on your fuel system. According to your diagnosis your bowl is running out of fuel. How did you determine this. Also you have two threads on this issue. you need to stop one of them. Can you post a picture of your mini including tank to carb.
