You don't want to do that. There are three main problems you have with converting this small of an engine. First of all you will lose 30% of your power by using gasoline over Alcohol. Second of all you would have to dilute your gasoline with a 30% oil mixture to properly lubricate your rod and piston bearings because they are sleeve type bearings instead of needle bearings.
