Engine does not turn off

My father-in-law picked up a 'free' sears push mower model 247.372550. I got it started, but it would not turn off when releaseing the handle. I have isolated the issue down to a seized cable on the blade control bail. I have tried several attempts at unseizing this cable, but have been unsuccessful. I see signs of rust on the cable. Is there anyway to unfreeze this cable, or best to just replace it?

One more question. This mower has a Tecumseh 143-424102. The muffler is in very poor condition. I removed it and did not notice any gasket between the muffler and the engine. Is it normal to not have a gasket in this area? I checked an online parts illustration (link below) and did not notice a gasket. Thanks for the feedback!

Just replace the cable, but it could also be a ground switch. However, realize that trash-canned lawn mowers can have more than one problem.

Mus: Follow RB's advice . You could hang the cable from the garage wall and spray some penetrating / lubricating oil down the cable sheathing and leave overnight , tedious job while attempting to free up the cable the next day . It could possibly re-seize later . Sears is good with replacement parts sourcing . Bring in the cable and Model Number / Serial Number . As for the Muffler some were machined surface without flange gasket necessity. Is there visual evidence of blowby ? You could make your own gasket if you feel it's warranted or again check your Sears Repair facility for availability :)
