Disregard.
I finally found one long screwdriver 1.5mm at another hardware store. Had to buy the whole kit.
Gentlemen,
This is the first time I am installing a cowling on a plane. I did my "clearences" ok, but how do you go about installing (tightening) the needle valve extension once the cowling is in place? [

I cannot find a long enough (3-4 inches) 1.5mm hex wrench at the local hardware stores. Don't know if this exists.
