Re: Max Speed/under carb throttle atops.
 

I have run the 1450 Max speed and it worked pretty good on my 622 with a lot of testing, then I switched to a 1150 Stinnett w #1 Stop, and that worked a little better w/ no testing. Now I'm running a Stinnett 1050 w/ #1 Stop and It's Awesome. (I didn't even adjust the idle on the 1050)

Both Gary's are great to work with, and answer their phones.

For what its worth, I have had zero mph loss by going to the smaller carb. I can run the stop lower with the 1050 and have it come on sooner. I'm a big fan of the smaller carb.
