I have the Dan Marc so I guess it is just what's in the bowl due to a dirty needle seat......I wanted a rebuild because the bike is 18 years old and leaks sometimes between the carbs. Annoying and maybe a bit dangerous.
how close to the T is the dan marc? There is a fair amount of fuel in the rails and pipes so I put mine right on the T
I have a set of float valves on the way as all 3 carbs on the left side are leaking a bit, number 4 quite badly but never had enough to stop starting....
runs very rich and splutters until it clears though, I have also been tapping the starter just in case as well, parts should be here this week for me.
O rings are pretty easy to replace on the fuel rails
