Ya, I'd suspect a carb thing leaning it out.

Running lean?
You should probably throw an impeller at it if you don't know the status
of the
one you have. There are 5 bolts right near the cavitation plate, 4 down
and one
up from the bottom inthe back. That drops the foot. Then the impeller is
in a
small can around the shaft.
