Fuel leaks

[(F5)]

We did a mates last month. Only thing that got it fixed was a new needle.

I drop a ball bearing in the seat and tap it to ensure the hole is round.

But do take your tap out and clean any tank grit. A hair will hold the valve open.

I have had good luck chucking up a cotton swab (Q-Tip), dipped in polishing compound (tooth paste in a pinch) into my electric drill. You can use this to polish the carb seat mating surface so the needle's Viton tip has a smooth surface to mate with or (with which to mate if you are opposed to ending sentences with prepositions) ;-)

This works brilliantly. We used autosol at the bike shop when we had grungey corroded carbs that were sitting around for years in the jap imports.

We replaced the seal/ball bearing tap after he'd tried this trick.
