" if you have to open the throttle, you have too much fuel.
Back off prime shot to -100, then increase start fuel until it starts reliably, even if it’s a longer crank time.....
at this point if it starts and then stalls, increase afterstart fuel until is doesn’t stall.....
Once this is done, then increase prime shot until it starts instantaneously, increase slowly,
only use as much prime as you need and no more.
Any prime shot before that point will be excess fuel."
