Hi David (and Marek),
I can't believe it's been so long to reply... I
gotta retire soon. I am way too busy now.
I like what Marek has determined, below.
A couple o' things to add:
- not just impeller but often the impediment to
cooling flow is a restriction between the block
outlet and injection to exhaust. Take apart all
the hoses and clean out debris with a wire pick
- the crab float shutoff thing is not uncommon in
old engines. I have outboard motors and
motorcycles dating back to the 70s. On some, to
rehab the carb/float situation it is simply a
matter of removing the carb gas feed hose and
spraying in a cleaner/lube such as WD-40. It
cleans any debris and gives a nice film to lube up the needle 7 seat on a carb.
If that doesn't work for your situation with
dropping gas in the stowed position. I suggest a
practical solution that I used in the summer o'
'08.. Simply rotate the power head so the tiller
handle/ throttle know is facing in the up
position. The carb won't drain out in this position.
cheers, Russ

My $0.02:
- Engine sounds as if it is running dry
exhaust. Crappy mechanic said it was a
"gasket"...where could that be? Its not an
exhaust manifold gasket... [MD] I would
suspect the impeller first (like in an inboard); they do fail.
- When engine tilted, fuel runs out of cowl
unless fuel shut-off closed. Said mechanic
said a "pin" was missing? [MD] the carburetor
probably leaks; my first suspect would be the
float and pin that closes the valve for the fuel.
