Craftsman lawnmower shuts off tried everything

[Mitch500]

Looking at the parts diagram i see this mower used a Primer system carb and a carburetor with a choke/no primer
does this one have a primer bulb you pump or a choke?

It has the Primer bulb

I'll

In your other pocket pop a can of carb cleaner.
The instant it stops give the carb a SHORT SHOT.
If it fires right up then you have a fuel problem
Let us know how you go .

Give it a go!

i have had a coil kill wire chaff and selectively shut the mower down when it manages to touch something, usually after it got hot so it was softer which i guess allowed it to touch.

this is why i say keep a spare plug in your pocket to test it, i never said change parts and "assume" anything, you need to find the issue, not keep throwing parts at it

for now unplug the kill wire from the coil and then go cut and see if it dies to eliminate a kill circuit issue since i doubt its the coil or plug if both are new

Will do, that's a great idea. Thanks everyone for the insight. I'm a pretty mechanically inclined guy but lots of these things suggested are areas I would over look. Thanks for the education.

Update:

Removed ignition coil ground wire and mower worked great. I guess I need to replace wire or inspect grounding lever.
