Andrew and Ilikeabikea have it down it's in the gears - but also there are some things you can do. First break the engine in. Always have a good plug - I think the NGK B5HS is about perfect. Good wire and boot. (you don't want to miss a cycle at all).
Next tune the carb as best you can. Or just buy a NEW carb - research the options. Then get a new head gasket and pull the head (and cylinder) per Norms posts. Do the wet sand lap job. You can get a better seal and slightly better compression ratio.
Use the highest octane gas you can buy. Use a synthetic race oil 25:1 or so. (I won't say add a little Castor oil yet)
Just a few things....read more in the speed forum!
