I added a 50 cc squirter and upped the squirter sizes. Hollow screw on the primary side. Not unlike a lot of other guys on here. Fuel pressure sits 5-6 psi. I have a return style regulator on the firewall.

Hit the throttle hard and it goes without hesitation. Accel pump is working alright. The issue I have is with slight throttle application off idle. It goes lean at tip in, especially if it isn't fully warmed up.

Also the idle screws are still maybe 3/4 turn and just don't seem to do much.

My biggest problem is I spend more time talking about it than actually tuning. Need to finish up a project at work so I can get more garage time.

I'd go with the Q-jet-not as fancy/cool but for what it sounds like by your needs, I'd give one a try at least!! prices/cost for them can't be beat as well. They flow 750 CFM as well.
