Hi,
I have an Ariens 1540H lawnmower tractor which ran fine for two months. Today, I let it run out of gas. When I re-fueled it (within 20 min) it won't start. It starts when I use starting spray (one of these things they sell in Home Depot, that you spray into air filter to force engine that won't start). But it dies once the starting spray vapors run out.
I checked fuel lines. The ones going from gas tank to air filter and from air filter to fuel pump have some gas in them. The one coming out of fuel pump to th e engine is dry. There were two other lines going to the pump and both had some gas in them, although I can't say they were full. I took the pump apart; it has a small membrane in it, there was some gasoline in the pump, and the exit "stub" leading out of it was free of obstruction. I put it back together but it still won't start.
So, I guess either the pump stopped working, or there's an air gap somewhere ? I am not good with engines, so any help will be greatly appreciated !
