Why don't you tell us *everything* you've done, so that we don't have
to go through lots of useless work on our part, like Don just did.
When you posted only 2 1/2 lines, I thought you knew nothing, but
maybe you don't understand how things work.
LOL, what I know about Briggs & Stratton is darn close to "nothing" but
I see (now) that its fairly simple. My bad, I suspected there might be
a common problem. Just removed the coil, (after using myself as the
Guinea Pig and getting nothing) and I'm off to the local LM shop to see
if I can get it tested.
Pulled the plug, opened the throttle to open the kill switch, held the
plug against the engine (as it was getting dark) and pulled the starter
cord a few times. No visible spark. Maybe I should get someone to hold
it while I pull? Just to make double sure? <g>
That's a good idea but :) ,,,,that someone could get a jolt without enough
juice to jump the gap. I suppose you of course tried a new plug. Other
culprit ( take it also that you don't hit big rocks, stumps etc) could be
the kill switch mechanism and the mag itself. If you have hit things large
enough to stop the engine then there could be an issue with the flywheel
sheer key being bent and the flywheel being just enough out of position.
I've seen this once and the engine did run prior but would not start after
I would go ahead and replace it regardless just to rule it out 100%
If you can, remove the wire from it, that would rule out a bad switch. Put
the plug back in and see if it starts. I don't trust 100% touching the
cylinder head with the plug body. I've been fooled by it on smaller tool
Back in 1983 I roomed with a buddy who work on small engines for
a living. He did lots of repairs on the weekends in our garage and he
taught me to work on this stuff so I'm not just making wild guesses here.
Very good :) Now I have to work on my Honda Harmony mower I sometimes use.
Not enough choke, single lever throttle/choke. It will run "almost" normal
with full choke. Won't start when cold so by those obvious conditions the
choke is not closing fully. Easy fix, probably and adjustment. Then it's
off to my Coleman generator of which the bowl needle valve is stuck (gas
pours out a tube on the intake.) Another easy fix, unstick the needle
valve :) We get some severe weather here in Tornado Alley and I've used
that generator a couple times too many since 2002 when it was purchased.
