The other day when tuning my carbs I noticed that if I hold the throttle open to bring the revs up to about 2.5 -3K that there is gas dribbling out of each of the accelerator pump jets. I always thought that the accelerator pump should not put out any gas until you actually move the throttle plate and only put out a spirt to cover the transition. I hold the throttle as still as I can but there is still gas dribbling out of the jet and falling onto the butterfly.
Has anyone else noticed this? Is it normal? What causes it and how do I fix it if it needs fixin? I bought these carbs on ebay a couple years ago and they've been a royal PITA. Additional info: Weber 40's 45 idles 28 vents 120 mains F11 emulsion 45 accelerator jets thanks, (IMG:style_emoticons/default/dry.gif) |

I've got the idle speed set pretty low and the gas does not dribble out at idle. It only dribbles out after rotating the throttle shaft a small amount and holding the engine rpm at around 3k rpm. With the gas not dribbling at idle, I would think that my float level and fuel pressure are OK and that there is a problem in the accelerator circuit???
