I took the carb off and found that rubber O-ring was broken. I assume
that was the culpret. I hosed down the carb with wd-40 and she started

stretched the spring or something but atleast it mows the lawn! Thanks
for all the help!

You can get a new o-ring at you local harware store for about 50
cents.
It's usually size 42 on the chart in the o-ring boxes.
I can look it up for you if you can't get a match.
