So I took my XR4 carb apart for the first time a few weeks ago just to see if I could do it and get the bike to start after putting it back together (don't laugh, baby steps.....). I bought the bike in December. Anyway it didn't hit me until today when trying to start it I noticed that it was leaking gas out the carb drain tube pretty bad but now I remember that when I took the carb apart that there was no plastic funnel thing that goes over the main jet. I don't know what the funnel is called but it's missing and I want to order a replacement. Anyone know what the part is called (or have a part #)? The bike starts and runs without it but starting is difficult.
