Yes. The crankcase pulse is required to get these carbs to work. If the walbro is a bolt on then the pressure port is likely to be in the right place. Even if its not you can tap the case and run the pressure line externally. The pressure port is in the same place on all standard walbro carbs.

Im about to hit the bed, early day tomorrow. But if you can hang tight until tomorrow evening i will break out the calipers and measure out these carbs. Im certain i have one with a 10mm venturi.
