I will post photos & explanations concerning the machined phenolic flow ramps that are added to the crankshaft's intake track. They are secured with J-B weld after machining & final shaping. They help the engine to pipe up & give an extra 300 to 350 RPM on the high end. Small size, front intake engines, can produce more power than a similar size engine with a driven intake valve because there is no energy lost in driving the crankshaft's internal valve. The crankshaft in the lower left hand side of the photo shows what the ramp looks like after the J-B weld is applied.
