I am trying to diagnose a no start issue and noticed that no fuel appeared to be coming out of the nozzle when the plunger is pushed down. I proceeded to remove the top of the carb and I noticed the plunger seems very lose in the bore. There is a lot of play at the top of the bore and the fit gets better as it goes down, but never really seems to get a good seal between the bore wall and the rubber seal on the plunger. Thoughts?
