Well, the stop circuit may not be working correctly….You could push the black/yellow powerpack lead out of its rubber connector, then ground it while the engine is running. Be careful though, that black/yellow lead will zap you.
If the engine stops OK when the powerpack is manually grounded, you will have to troubleshoot the stop circuit wiring/key switch, etc…
If the engine still fails to stop when the black/yellow lead is manually grounded, you will need to replace the powerpack. I am "asssssuming" the powerpack is grounded properly though.
