Bigger Carb....bigger Jet and bigger 150 Intake Manifold will not equal more speed and power.. A stock engine is only 50cc(3.05 cubic inches) and even a true 80cc BBK stroked is(4.63 cubic inches) Therefore the most fuel/air you will EVER be able to draw into that engine per stroke is..50cc-80cc(3.05-4.63 cubic inches) Think about older car engines..they were 305-460 cubic inches for the Ford series anyway...and they could have a bigger Holley carb on them for extra power. But on a tiny engine like ours...it would take exactly 100 Scooter engines to equal 305 cubic inches.(same as the 5.0L engine) For more power you need ..more rpms..more displacement...Nitrous Oxide..Nitromethane based fuel.. All of which will grenade your engine. A 24mm carb and 150 intake are overkill and will not do it...the engine simply CANNOT draw in that much air/fuel. Therefore I would opt for the 'Road Runner' cartoons ACME Jet Pack..
