Yep, BP6ES it is for standard engines, however he doesn't seem to have much trouble with the other popular brands as well. I think the key is start with something close in a brand you like, then make adjustments within that brand or close alternatives until you find what works best for your engine.
Having said that, I have no idea what works best for my engine! Hopefully I'll be able to find out more this spring when the wx gets better.
