Thanks for the reply!
There are NO vacuum leaks... ALL the caps are new!
I've checked for leaks with both carb cleaner and starting fluid... there was NO change in idle using either type of spray.
I'll pull the shims this weekend and see if that makes a difference.
I'll have to order the larger jets as I don't currently have those sizes.

A question...
Previously - using a float height gauge, I had adjusted my floats to the recommended 17mm height. When I checked the fuel levels - using the sight-tube method - fuel was just above the top of the gasket flange (~2.5mm above the flange face).

I've since adjusted my floats so the fuel level in the bowls is right at gasket flange.

Do you think the fuel level in the bowls is contributing to the symptoms I'm experiencing?

Regards!
