[AT] small engines

[Cecil R Bearden]

I don't know why the water is in there either.  It was more than a 
quart, so that is a lot of condensation.   It was outside, but the cap 
seals well and there is not an air hole on the top.  I have a honda 9 hp 
on a cpmpressor on my service truck.   It is outside all the time. After 
a rain, it would have water in the cylinder & carburetor,  I finally 
drilled a hole in the exhaust manifold at thev very bottom and it sorta 
stopped.   However we have not had a prolonged rainfall in a while.  The 
bottom of the briggs carb where the brass plug that holds the fuel bowl 
on is less than a half circle.   it is shot!!  The fuel valve was off 
and the carb had been run dry.  Is there something I can put in the tank 
and leave in there until I need the engine?
