Motorcycle carb on a sprint, Is it possible?

Hi

Is it possible to use a carburetor meant for fourstroke motorcycle on the vespa’s twostroke motor. If it’s not possible then why is it so?

I have one with an accelerator pump lying around here and wanna try out, but i want to make sure if it’s worthwile before i go for a suitable manifold.

Not just by bolting straight on. I had this problem with my lambretta . 4stroke carbs have a different atomiser to 2stroke which makes it almost impossible to jet it up correctly, but it is not a big job to swap it although with the cost of new atomiser, needle and various different jets it will probably be cheaper to buy a new carb. I think they also have a different slide cutaway too.[:(] Hope this helps.
