Could be, in addition to the other suggestions, a worn float needle/jet. A
"rebuild kit" from an autoparts prob ably wouldn't cost more than $5-10.00.
If you can get it, just replace the float needle and jet and gasket (if you
must), and filter.

t.ca...
I have a Merc I/O, probably about 10 years old. It has been tuned up and
has
been running fine. But it tends to stall at idle speed and sometimes will
stall when you throttle back after running at speed.
Carburetor problem? Dirt in the gas? Electrical? Something simple or
should
I haul it to the service guy?
Thanks.
