on spark replace coil and plug no spark,. then check my 460, it runs, with plug out no spark why is this?
Okay, you know what you are meaning by what you typed- but I sure as heck cant fathom it.
You have a 1981 model 50 that had NO (not on) spark so you replaced coil and spark plug- still no spark?
Your 460 does currently run but with the plug out there is no apparent spark?
My guess is the 50 has a stray earth problem and the kill circuit is in a permanent "off" position regardless of the switch position- or the switch itself is faulty and not returning to run.
The 460 is not getting a good enough earth to the cylinder during your tests and or the flywheel is not being rotated fast enough to produce good visible spark.
