Blazer won’t shut off with key

[Scompton73]

Got an issue with my blazer where I turn the key off but it seems only one cylinder shuts off. I have to pull the choke out to kill it. Any ideas?

Do you throttle it down then turn off key?
Try turning off running full throttle

Tried throttling down, no luck. I think the issue is either the relay switch or the key switch itself. I may need to replace.
