Thanks

So does anyone know what size head shim I should use?

With that, you'll have all sizes.

Your manual should say what size shim to use. For my Picco .28, it said to add 1 0.10 shim for 30% fuel... I never did it though.

Too late, but thanks anyways. I called up hobbytown and they said to add a .10 shim, so that is what I ordered because they couldn't.
