if that's all your painting you'll be fine with a good high-temp spray paint. just get a good can from an auto parts store. i've painted a couple of engines like that no problem. after sanding i used 2 coats primer, 4 coats paint (overkill i know, 2 is fine) and 2 coats clear sealer. i only painted the metal shroud of the engine though, the part that i could un-bolt and remove, not the entire engine. i would simple green that and hose it off to clean up. good for cleaning deck to. a lot less work than painting EVERYTHING and i think the end result will be very nice!:thumbsup:
