Setting up my Carbs

Post by Borotosh » Sun Apr 26, 2020 11:25 pm

Hi All
I have played around with my roadster, tappets done, timing done, new plugs, air filter cleaned and decided to set up my carbs as plugs and exhaust are black.
I have balanced the carbs by ear and set the mixture with a colortune, tried to set the mixture at the weaker end but it didn’t like it, ended up having to set the engine just below the yellow flame, runs nice but still have black plugs and exhaust.
Something I could not get the engine to do was when lifting the “lift pins” or carb barrel was to get the engine revs to increase or remain the same, the revs always dropped???
Any Suggestions?
