Rookie question: I have a spark knock when my HH250SS is under load (i.e. Loose Sand, hills) I've tried octane boost and replacing the plug, any sugestions would be appreciated. No jet upgrades and stock breather. Thanks

You might just be lean. The stock jet is only a 108 probably for EPA reasons. Try a main jet a couple sizes bigger or better yet ditch that stock air box and try something in the 125-135 range. If that doesn't help your base ignition timing might be off but not likely.
