The Evo .46 has the same nedle set-up as a Magnum and will move to the front easily. I did it to mine.

You guys can have your rear needles. I have had too much trouble with mine except on the OS AX. As soon as I moved the needle to the front, all my erratic running quit. I have run an OS .91FX and several Magnums. The OS, I put a K&B on and everything else got converted. Let's say the banjo fittings are not my cup of tea.
