QuestionQUESTION: I think Ive determined the carb is gunked up on my js63. First hint was it starts after primed- but quickly dies. Second hint was I forgot to empty the gas tank in the Fall
I also noticed some fule leaking from primer bulb? Not sure whats causing this?
Anyways- heres my question: Ive never disassembled the carb before. I tried just loosening the nut under the fuel bowl- but gas started leaking out...
Do I need to cutoff the fuel somehow?
Do I try to remove the carb assembly instead on just removing the nut from under the bowl?
Help!
ANSWER: If fuel keeps leaking from the primer, then the float/needle inside is sticking, and you need to remove the carb and disassemble, if not
just remove the nut on the bottom of the carb, fuel will dribble out.
You can pinch the fuel line with some vice grips, or remove the air filter, and tilt the mower up with the front wheels up, and remove
the nut on the bottom of the carb, hopefully the bowl will stay on,
and clean out the tiny holes in the bowl nut, and reinstall.
With luck, that is all you need to do to get it going.
If not, you need to remove, disassemble, and clean the carb.

QUESTION: Worked! Running now... but idling VERY slow. Any idea how to adjust the idle? I can manually pull the spring/link back and rev the engine- but Im not seeing how to make an adjustment?
AnswerThe throttle control moves a pivot that puts tension on that spring
when the throttle cable is moved, adjusting that is usually done by loosening the clamp holding the cable and moving it. Or possibly the
arm that holds the spring has been bent and needs bent back.
I will need to have your engine's model numbers to be more specific.
