Is there a place where I can find an explanation of the way the regulator and needle valves work? The YS site and everyones advice is always to turn the needle or regulator screw this way or that, but if I could understand how the engine works it would be most helpful and make it more clear why the adjustments are needed. Thanks, Steve

If you want to know, call me sometime at 775-265-7523. I have written it out too many times on this forum and it always ends up with more questions. It's just quicker and easier for you to call.

Thanks, I'll do that sometime. Is there a time when its best to call or just whenever?

Best for me is between 9 and 10 west coast time any weekday morning.

I'm happy to explain the whole nine yards!
