Thanks for the reply. I am almost sure that I have a fuel pump.
Also, this is a new problem and I have had no problem mowing this
sloped land for the past 2 years. Generally I start off with a full
tank. The fuel filter was changed recently. I did manage to almost
run the mower out of gas a couple of weeks ago and you may be right
that I have air in the line. How would you go about purging a fuel
line of air? THanks again for the reply.
