    915B won't start

    I have a 915B 60 inch mower that has run great for the 3 years I have had it. Got on it yesterday and it wouldn't start. Turns over but that's it. Changed the fuel filter and plugs and noticed there was no fuel getting into the filter. No fuel runs from the tank to the filter so I blew into the line and heard bubbles in the tank, line is clear.
    What can cause the fuel not to reach the filter and subsequently the carb?

    If you put a little suction (I am not suggesting using your mouth!) on the hose coming out of the tank, does any fuel come out? A slight crack in either the hose inside or outside the tank may prevent fuel from coming out (drawing air instead) though blowing into it will still cause bubbles to come out the other end because you are "overpowering" the small crack.

    Just my 2 cents, good luck.

    Is the tank full?

    I read someplace that the fuel pickup line (#2) can cause trouble.

    Good point, I will add that depending on where the fuel pickup hose (assuming there is one on your tractor) exits the tank, a full tank can "hide" the problem. Fuel level above a cracked line will just take in fuel until the level goes below it. Then if you're mowing, sloshing around at that critical level will make the problem intermittent or cause rough running, or even no problem if your fuel pump can keep up. Then you drive to park it and the carb bowl empties or evaporates due to engine heat after shut-down and you can't start the next day.

    Just a thought and more 2 cents.
