      Check your mixture screw first - that's even easier!

        Ya I'll play with that tonight. I noticed the caps were off before I cleaned them so someone's been in there already.

          If you didn't set them correctly that's a likely problem, but also if you didn't take them out to clean the carburetors that's another likely problem.

            And you didn't turn them in to find out where they were set and then remove them when you[soaked] them over night . Sounds to me like you are cutting corners, what you will need to do is a complete tear down of the carbs, dip and clean them thoroughly, replace the o-rings, do a bench sync, then reinstall, then do the final sync and tuning. Something is dirty in the carbs. If you follow the tutorial they will work fine and your bike will run smoother then you can imagine it just takes time and there are no short cuts. Good luck

              That's right everyone - I did not take the mixture screws out when I soaked them. Bad boy. Cutting corners to save time does not always save time. I'm still going to start with the easy stuff.

                Even if you clear up the immediate concern, your carbs are still filled with rubber O-rings that have been soaking in gasoline for 30 years. Best to change them now and cross that off the list of possible future problems.

                  Not to mention that if "soaked" means you dipped the carbs with the o-rings in place, they are likely trashed now since the carb dip eats the rubber.

                  What did you soak them in overnight?

                    Honestly, I'd back all the way up and start over or you'll be chasing your tail for awhile. It's a lot faster to do it right the first time in the long run (says the guy who's still learning that fact when it comes to electrical issues).

                      Thanks everyone. The mixture screw was almost falling out. Set it to 2 turns out and runs great.
