Basic carb setup
Posted: Thu Nov 19, 2009 7:28 pm
Had my carbs ultrasonicly cleaned [thanks Ginger Bear] and have now reasembled them ready for refit. Whilst setting up the slide heights I have noticed that if I set them all at 0.7mm from the notch to the venturi when the slides lift up to the fully open position two slides clear the venturi before the others. If I set them so they all clear the venturies at exactly the same time when they are in the shut position you can see that no2 is lowwer than the rest. I know if the no2 slide is adjusted too much you can lift the other three as when the slide bottoms out it rotates the common shaft and lifts the others this is definatley not the issue. I would like to know which set up is the most important level at top or bottom 
my idea is at smaller throttle positions any differance would be critical as against full throttle where the percentage differance would be less.
any ideas welcome. I would just add there is no chance any parts could have become mixed between each other as they were all kept in sealed metal tins.
