Can't get it to idle right!

Thanks, all for input:D

I think your on to something there redfish. I have a clear filter, and it does look like it's running out of fuel. What did you do to fix this?

Same things factory did. Reroute fuel line, relocate fuel filter, thicker base gasket under carb. And of course make sure the bowl vent remains open when throttle is on curb idle stop. That adjustment varies with carb type.
When my base timing went up, curb idle went up, backed of idle stop, vent closed.
