Hey Charlie -

I saw that on eBay but I don't think that is a good replacement for this 670.  For one the thumb knob bit isn't correct for this engine, it seems some 670's (like mine) have a "rubber" like bit around the knob.  Also, I am not impressed with the brass screw, as that will bend on its own over time from the heat.  Which is a problem with the Empire throttle screws that are brass from the factory.

I got my straighten enough, so it works okay now but thank you for the suggestion!
