Bob, I didnt take it apart the carb, I give it a try by loosening the
1/2inch nut found on the carburator bowl bottom and draining the old
gas. (I was expecting the carb bowl to come apart, bit it didnt, thats
good since its not that complicated to put the nut back). And flushed
it with Isopropy Fuel Dryer and soaking it overnight with STP Complete
Fuel System Cleaner following it with fresh gas. It worked well. Thank
you Bob for the tip.
