[QUOTE="Monkeypants, post: 118752, member: 2708"] Goldstar technology! Roland Pike was in on that accidental discovery. The story goes that Roland was setting up and tuning a works Goldstar for some big race. The apprentice was sent to retrieve a carb to fit. He mistakenly grabbed an oversized carb and Roland mistakenly fitted it. The dyno showed a good sized increase over the normal works Goldstar output. At some point they realized the had the wrong carb. They fitted the correct carb and the power went away They re-fitted the wrong carb, the stepped carb and the power came back. Something is going on here! They tapered the intake stub so that the step was gone and tried the big carb. The power went away again. So the step stayed. It's like the bulbous bow discovery. An accident between two freighters created a bulbous bow in one and added 4 knots to its top speed. Now all big ships sport a bulbous bow. Glen [/QUOTE]
