Good Day all of you!
Yesterday was a big day, finally got my 1976 CB400F running after about 15 years of sitting idle. Bike turned over like a champ but is running rich. I have grey smoke coming out the exhaust, and it wont hold an idle. I can rev it no problem but as soon as I let go of that throttle it stalls. Just had the carbs rebuilt and timed.
So what's the next step? Do I try to mess around with the fuel screw on the carbs and adjust those? Look for vacuum issues? Or do I just yank those carbs out and start taking a look at the float bowls, needle jets etc?
Your help is much appreciated. I'm sure this is a pretty common problem...
