the chain has to have stretched a lot to jump teeth, if it's not stretched ie correct tension it can't jump. now installed a tooth out? that's entirely possible, lol.
I've actually watched an old stiff one of those link-belt timing chains, walk a tooth over, when the engine was rotated backwards, - like when shut off, the engine "runs on" then goes whoof, with a shot of something outta the carb.
The engine actually runs reverse rotation, and has/does walk an old stiff timing chain over the cam sprocket. It'll push a straight section of stiff chain straight UP, - till it finally flops over, - a tooth over from where it should be .
