I have an older Snapper walk behind mower that has run fine and always
started on the first pull. Last week I ran over some tall grass and the
engine choked and stopped. It wouldn't restart.
I started troubleshooting and noticed it would start and run with the spark
plug wire disconnected and set about 3/8" from the spark plug. If I move the
wire closer it slows and stops. This seems to be a timing issue.
I pulled the flywheel but the key is fine and not sheared. The motor seems
to have solid state ignition as I don't see any points or mechanical advance
Does everyone agree that it is timing? How do I adjust the timing on this
type of mower? There seems to be no markings. Also it seems pretty
convoluted as I have to remove the shroud/pull start adjust, then put it
back and try it repeatedly.
I am still at a loss to figure out how it got into this strange state. What
could cause the timing to just change that drastically.
Any help is appreciated.
The key does not have to be sheared. If it is bent the slightest, it
needs to be replaced. It should be clean and unmarked, usually square
in cross section. If it is not square, replace it. It will on ly cost
about a dollar to try.

The plug wire issue the OP is experiencing is helping the spark to
jump across the (probably misgapped) electrode with the right power
level to ignire the F/a mixture.
I had a Ford that sometimes needed to be started that way...on the
coldest days. TBIs suck. <G>
I guess I'll try a plug, but I see the spark jump the gap on the plug when I
pull it out and ground it.
On a Tecumseh engine with solid state ignition, timing is adjusted by
adjusting the distance between the flywheel and coil assembly, so i thought
the same might be true on this B&S engine.
