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?
