You're gonna have to provide more details: how the carb is getting fuel; the mixture; the jet sizes; any manifold, gasket and other vent porting.
Start with pics? Maybe start by showing how you resolved the intake leak at the gasket, and go from there.
Also did you buy this vm22 new? Has it been modified already? Was it advertised as plug and play?
It's anybody's guess why you're not out scooting around in the rain today.
