I,ve made up lots of main needle extensions Many older needles had a nub for a solder on tube and of course the modern method with a wire or allen locked in a set screw-However-only long enough to clear any cowling and no more.

I do not want anyone around me approaching any running engine with any long object, screwdriver, socket or old piece of tube I don,t care I don,t want to look at the blood.
