[SEL] carb_fueling problem

[R and E Freeman]

Sounds like the carb fuel flow is restricted and if tapping the carb helps
its likely that the needle and seat is sticking or partially blocked

Subject: [SEL] carb_fueling problem

I have a Kohler CH18S engine, 18 HP V twin

when I start it, it will run a few minutes then run out of gas, seems that
the
needle seat was sticking closed and not allowing fuel in so I pulled the
carb,
cleaned very well, installed a kit, new needle valve etc.
I am running an electric fuel pump.

Afetr I rebuilt the carb, it started and run fine but may do so far 2
minutes or
30 minutes?? then will run out of gas. I can peck on the carb and it will
run
again for no telling how long, yesterday I could not keep it from doing this
when
I started it up and stood there and tapped on the carb every 15 seconds or
so as
that is how long it wanted to run, it would stay runing as long as I done
that,
then it leveled out and started running on its own but would run about 10-15
seconds and start acting like running out of gas but would pick up on its
own ,
finally I walked off from it running and it came vack in 20 minutes it had
died, I
tapped on the carb and started it up, then it ran all afternoon, about 4
hours

what could be the cause of this and what can I check out or try to do?

the carb is very clean inside?

Clint
