Had a sod of a time tuning it earlier today. It's close but not right.
Now I'm not ready to give up with the pump just yet. I ended up today with the low needle about 10 degrees leaner than factory settings. Mid and high needles at just about 1.5 turns.
Its reasonable at high speed but bouncing on the pipe in idle. Picks up great on spool up but hangs on throttle down. Seems really hard to find the sweet spot so any advice or just give up and remove the pump ?
