I had an old CB with 4 carbs, I bought an old book on motocycle maintenance and it had a DIY method of balancing carbs using jars and tubes. Basically you just run the pipes from jars (filled with oil) vertically up some wood and then onto each carb. The vacuum pulls the oil up the tubes and you adjust them as required. (I never got around to actually doing it though )If we weren't talking about troublesome carburetors that would freak me out. :lol: But I'm intrigued. Can I use those MacGuyver-esque supplies to sort things out?
Here, I did a quick search...
Or you could buy one.
