ok, but after taking the carb apart and making sure it's squeaky clean, reset
it.
the gas we've gotten in the past 20 odd years is shit and turns to crap in as
little as a month. so clean the carb. if it's been sitting for more than a
couple of years, i would get a rebuild kit.
at the same tims, to save future problems, clean the petcock and check inside
the tank.
water in gas=RUST.

thanks. done all of the above except rebuild kit. been looking for a
complete carb (new or rebuilt) on the net with no luck. actually, i had carb
"professionally" cleaned and i cleaned and refinished the tank. appreciate
the input.
