New to me (used) carb, same issue.

Installed the Mikuni VM 28 (flat slide even though it's designated as a VM) and am having the same issue.

Run the motor, shut it down, wait 2 mins and the fuel starts bubbling and pouring out of the overflow.

I'm going to install a new needle and seat, but doubt that will change anything. It didn't fix anything on the last carb. (VM 26-606)


On a good note, it seems to be running pretty good thus far.
