Default how can i make supercharger for 4hp-100cc-2stroke-engine?got a idea please give sugg.

I took an engine out of a snow blower (a 100cc-4hp-2 stroke) and was planning on hooking a leaf blower turbine/fan up to the carburetor. I plan on taking a 200/300 watt electric motor with a speed controller (HOOKED UP TO TWO 12VOLT 12Ah RECHARGEABLE SCOOTER BATTERIES) and connecting it with a 60 tooth pulley attached to the electric motor and a 12 tooth pulley from the turbine...

I would mount the engine on the end of a electric scooter and mount the supercharger (leaf blower turbine) on the side then run some sort of tube/pipe to the carburetor from the turbine. The batteries would be under and inside the scooter. The supercharger would most likely be used to add acceleration upon take off opposed to using it at the engines max power for top speed.

Do you think it will work?
Any thoughts or suggestions?

Since superchargers don't work much on 2 stroke engines because the exhaust ports are open at the same time as the intake ports are, is it possible to build pressure in the cylinder using a supercharger?

This over-pressure air into the carb will stop the fuel flowing past the needle valve (venturi effect needed to pull fuel into the inlet airstream will fail - unless you pressurise the fuel tank by sealing it and fitting a tyre valve then pump it up before opening the fuel valve).
