HI i drive the rail a lot during summer it is street legal. the buggy does not run rich now! it had 60 idles and i went to 50 idles. weber suggest"s 55 idles for a 44 weber with 36mm venturi! but the buggy shop was out of 55's, the motor no longer loads up while idling, it runs smooth and the acceleration is crisp and potent sounding, my plugs are tan color know!! they was black and sooty when i was running the 60 idles in there so i think it will be all right, took me a long time to get this thing to work right!! i turned the adjusting screws till i wore my fingerprints off

the adjustments are real sensitive know with the 50 idles the motor responds well to them the 60 idles you could turn the mixture screws all day and the motor would not respond at all thanks
