Next meet I'm bringing my timing light and metering rods for you Pros and we'll play a game of "Who Can Get It the Closest". Hopefully by then the points system will be gone though. Winner gets an ice cold beer and a pat on the back.
It's a Carter/Eddy style carb? 650? Changing rods and even jets in that style of carb is easy. It is knowing what to change them to that is the hard part.
