So the engine runs great with the new electronics. (and the Halls sensor was set at 28 deg, btw). But the problem is it takes forever to pull fuel when I'm trying to flip-start it. So I looked at everything again - the carb, the tank, the lines. Now, with choke closed and throttle WOT, it won't pull at all (when I flip the prop by hand). With my other DLE 30 and 35 it usually takes 10 flips the first time for a "pop", then another 5 with the choke open to start. Now - with this 30 - it's not pulling at ALL when I flip the prop by hand. I then tried a starting and 22 volts of power turning that spinner QUITE fast, and it finally pulled fuel, and quickly, to the carb. A few more hand flips and it started, and seems to be running fine now (both needles now set to about 1.5 turns). But I should not have to rely on a starter motor. So - question - why am I not pulling fuel normally? Could the carb passages be dirty? If so, how do I clean those? Could the metering level not be high enough? (though I measured it with my Walbro gauge, and it looks correct).

Thanks.
