This thing works great right out of the box so I haven't even tried it yet. Even came with a fuel filter. I added an Aeromotive fuel pressure regulator (13205) with a fluid filled gauge. Be sure to vent the pressure gauge before adjusting the pressure to about 6 psi. I reset the float levels before installing and the cold start idle is a bit high and needs to be reset. But with this new carburetor, it idles even better in cold weather. And the exhaust fumes don't even smell too greasy anymore.
