Thanks for the replies,
The mower sat untouched for a couple of years. BTW, It is a 4 cycle
engine and the gas cap is off of the mower right now.
I tried some carb cleaner after reading this but it didn't seem to
change anything, Passages appear to be clear but there are some "ball
bearing" type valves in the body of the carb. that I think may be
still clogged. I don't know if those bearings are supposed to spin
freely. They don't
My fear is that I'll have to replace the whole carb.and that a kit
won't help me.
