Re: almost closed petcock gives me more power
You'll notice that when it runs out of gas it will rev HARD before it dies. This is not good for the engine. What yer doing basicly is starving the engine by shutting off the gas. While I think yer running way too rich, Running it TOO lean is worse. Check yer float and inlet needle valve. Last resort is a smaller jet after you try everything else. DON'T run it like this any more. LISTEN TO 2door.
