Question about Craftsman Garden
I have a problem a Craftsman 18hp 42 in deck, 917.273762. It appears the engine isn't getting gas. It just stops running. Fuel filter has been replaced. All other filters are clean. The plastic/glass in the fuel filter line has no gas in it when the tractor stops running. It seems to happen after running for more about an hour, as if it's because it's hot. Let it sit for a period of time and it's good to go--but only until it's hot again --or whatever is causing this. Any ideas?
The problem is called vapor lock. It occurs when the fuel in your supply line is vaporizing just before it gets to the fuel pump and the fuel pump is not designed to pump vapor so you run out of fuel.
Possible solutions are to re-route your fuel line so that it doesn't get hot from the engine and/or run the mower during the cool parts of the day only. It might be as simple as getting some new gasoline as winter bought gasoline will always vapor lock if used in the summer time as they alter the formula for gasoline on weekly basis to stay ahead of vapor lock problems nationwide. Way back when cars were mostly carbureted it was a MAJOR summer time pain. The three options given above remain the best solutions for this ages old problem.
