Turn the idle mixture screws out another 1/4 - 1/2 turn and try it.
I missed this message initially. Should the idle mixture affect it at higher throttle/rpm?
My list for today:
Check for vacuum leaks
Adjust idle mixture as above
Hand block it to suck out any debris
Drive it to get it hot
I will give it a try this afternoon. I will plan on checking/adjusting the float when I rebuild it.
