Do you have any .025 welding wire?

If you do, cut a piece long enough to fit in the bleeds and loop around the bowl vent tube.

Sticking the wire in your current .075 bleed will make it about a .070-.071. Observe how the engine reacts. If it needs even smaller, stick another wire in the bleed or a piece of .035 wire. That will make the bleed about a .067-.068
