I'm trying to get an old Simplicity S6 snow blower going with a B&S mdl 146402. I don't seem to have spark. When I check continuity from the stop wire to the engine it seems to be grounded. But then when I unbolted the old style armature the continuity is broken and then when I pulled the throttle to stop it grounds. But as soon as I bolt the armature back on it's grounded is that normal? I haven't pulled the fly wheel off yet. Can it be grounded back by the points? The armature has a small bare wire with an end that gets connected to the mounting bolt but it shows continutiy to the stop wire when it's not mounted. Should it?

 

Yes it'll ground thru the points... It's probably time for a points & condenser set to give the old Girl a treat anyway,, isn't it?? LOL...Roger
