Yes, but not a great amount.

I have a Poulan Pro riding lawn mower. It has just started having a
problem that I need help diagnosing. It is some kind of a fuel
problem and is related to the position of the mower while cutting. My
land is sloped and, when cutting the following happens.
If I am cutting across the slope and my left side is on the downhill
side of the slope, the mower gets plenty of gas and works perfectly.
If I am cutting across the slope and my right side is on the downhill
slope, it slows down and seems to lack power. It almost slows to a
stop. The fuel pump is mounted on the left side of the engine. Any
thoughts about what is going on will be appreciated. THanks

Does it smoke when it slows down?
