5.5 hp Brig&Strat vertical shaft lawn mower engine not starting.
Original problem ...
When starting it went straight to full throttle mode for a few
seconds then died (like hitting a kill switch).
I found the throttle valve was stuck in full on. I gave it a
little nudge and it was working smoothly.
Then i broke the pull cord trying to restart.
I fixed the pull cord and re-assembled top.
New problem ...
Now engine won't fire or huff or anything.
If i use the gas primer bulb and pull the plug it will be a bit
wet. So I checked spark on the plug. The sparks are there nice
and bright although maybe a bit orange. I checked the spark with
an automotive spark gap tester , it gave a bright spark out to
about 3/8 " (1 cm). Air filter seems ok. Took float bowl off in
case there was water and no water. I drained some gas out of
tank in case there was some water there.
If i spray some starter fluid in the carburator (yes, air filter
removed) I might get a small huff or fire but that is it.
Occasionally i get what sounds like some backfire/cough ??? So i
checked the safety/sheer pin on the flywheel to make sure it had
not been wrung/spun. The pin looked looked fine ,not budged in
slightest bit. The coil to magneto flywheel air gap looks nice
and tight i measured 10 - 12 thousanths (.010-.012) ".
So what am i missing ? what to check or do ?
thanks for any helpful replies.
