Had a panic moment, lost the piston to my 7910 cylinder. Searched high and low, then remembered I left it in my car when I went to the shop last.

Ill keep track of it better now :cursing2:

John, I have some extra low matte black covers I'll donate to you if you want. No offense I'm not a fan of the silver

:nusenuse:
I'll take you up on that! I don't like the silver either.
How's she run
It runs good, first time I have ran a 6400. They pull well for being 64cc. But this one is getting a 52mm top end eventually!

So what's the preferred carb on the upgraded 6421/7910's? I heard about some carb mods from @Poleman. Mine is a Zama that is below.

Pull that lower cover off and see if its a twin jet.

Then you can drill the jets based on the mods to your saw. Tutorial on one of these pages I posted from poleman.
