Thanks Tom...I didn't plan to use the key ;) hence my 2-for-1 tool hunt.
I don't have a 22mm wrench, so I'd have to buy that too...am still hoping to get an answer about IF I can use a deep 27mm socket for both.
If my ship comes in, or the family is generous at xmas...I can probably spring for more tools ;) since "small increments" sounds like a bonus. I hope to hit both pawn shops (as per Nate...can be good cheap tool shopping) and the PAP after xmas. And come to think of it, it's not too likely I'll actually get to the valve adjust before then...
And much thanks for the warning about the nozzle pressure...yikes!
