I recently started to get my new to me moped ( 98 tomos targa ) running finally. I ordered a carb rebuild kit and used all the pieces and I fired right up ,unlike before when it would only run with the choke on and throttle 3/4 way open. Unfortunately as excited as I was for this I noticed fuel spilling out of the carb from all over , like it was flooding . Realized that the new needle valve was only half the length as the old one . So I decided to just put the old back in expecting it to be good and now it’s like it’s not getting fuel again like before. Do needle valves go bad ? I think I’m going to order a new one specifically for that carb .
Any advice would be greatly appreciated, thanks
