Hi
I am going to put a 25cc Toro into a car also. I am going to leave the plastic housing,clutch and flywheel in place. This will give me a clutch and good cooling thats required. The pull start will also be retained. If you look at how some of the guy setup their boat motors on the net, you will get the idea. Think that I am going to cut down the plastic in the shaft area, so that I can mount a sprocket in the clutch drum. I can use a bike chain for drive giving easy gear ratio changes. Now all I need is a good used quarter scale chasis.
