A little off topic i have this harley wich is supposed to use a vaccum operated electric switch for the timing advance.
My question is does anyone know of an adjustable voes i can use off something else as a substitute.

There are hobbs branded switches around, I have used them for meth injection under boost. There are vacuum models avail and are adjustable ... http://content.honeywell.com/sensing/hs ... switch.asp
