Q320 rehab / mod?

[addicted-to-smoke]

I still need to find the right size needle or drill bit for the burners. My Q300 only gets up to about 400-450 now, not "bad" for most any cook, but many of the orifices are corroded/partially blocked. And so there are a few hot spots like at the ends. I barely used the thing since cleaning it up and if this is what happens just sitting around I'm even less inclined to keep this grill.
