One thing I rarely hear talked about is how to accelerate. Beginners tend to stomp on the throttle at the apex. All carbureted engines will accelerate faster with a more gradual opening of the throttle the slower the speed at the apex the more gradual it should be. Slamming the throttle open lifts the metering rod from the main jet making more fuel available the problem is that it also lowers the vacuum which makes it impossible to pull the fuel in until the RPM comes up. When it’s extreme you feel the engine bog but it still may be happening even though you don’t feel it. Lowering the connection point of the throttle on the pedal and putting it closer to the pedal pivot point gives the pedal more throw and makes it easier to control the throttle. This works great with some beginners.
