the big screw on the side is the main metering jet adjustment. The initial adjustment is 1 1/2 turns out. the idle adjustment is on top of the carb as you turn it in it will open the throttle slightly to make the engine idle faster. You should tape up that wire so that it doesn't ground out or spark near the gas tank . That is for a kill switch. There is a jet behind the metering screw on the side of the carb that you should clean. Just take the metering screw out with the nut that it's in. Then you can remove the jet. use a piece of wire to clear out the hole in the center. The only other thing that causes problems is the pickup tube screen inside the gas tank. You get to that by taking the carb off of the gas tank. The briggs engines are easy to fix and work on and is a good one to learn on.
nice bike, I'm glad to hear that you got it sorted out. Looking at it makes me miss my bonanza chopper.
You should put that square metal cover back on the side of your engine. It's purpose is to direct cooling air from the flywheel to the fins around the valves. That will keep you from burning the exhaust valve. Ask me how I know this.

yup, I burned a valve so bad that it had a big V burned into the valve where it cracked. I heard that the exhaust valve can turn cherry red when the engine is run hard. especially if there is no muffler on it. Briggs lawn mower engines burn up when the fins under the cover get clogged with grass. Try contacting the restore kid who is a member here.
