It may also be water has gotten into the gas/fuel/petrol
tank. It's winter here in New Hampshire. The usual warning
is keep your tank full, to minimize condensation of water
on the steel walls of a cold, empty tank. The water sinks
to the bottom of the tank, where the fuel line pickup sits.

Try a can of "dry gas" (isopropyl alcohol) in the tank. It
absorbs the water and let's it "burn."  This is probably
the cheapest and easiest solution, if it works for you.
