Fogging oil...

Wondering what others do. Last time the chopper was running I pulled the air cleaner off and sprayed some fogging oil into the karbonator. Shut it off, put the filter back on, put it on the lift and pushed it into the back of the garage. Once a month or so I pull the plugs and give each cylinder a healthy squirting prior to rotating the crank 180*. First start up in the spring is always a bit smoky.....
