Motion Pro makes the tool you need, it's a torque wrench adapter with 12 and 14mm sizes. Dennis Kirk has them, Part # 28-729...

my esr330 I'm using a 188, specail needle for it, and 55 pilot an runs a bit rich. I'd say start with a 180, 55 pilot and richer needle. those pro-x piston kits are expensive, so don't screw it up.
