I have a JD LX172 with a 14 HP Kawasaki Engine that was my dads.The last time I ran it it would be running fine and then would just die and would not start again for about 15 minutes. I would notice that there was little to no gas in the filter when I would crank it. Then minutes later it would start and go for awhile then do the same thing again.I am wondering if this could be the fuel pump? The motor will start right up when you prime it and keep pouring gas into the carb. I took the pump off yesterday and cleaned it but I still do not see any gas go threw the filter to the carb.Any way to check the fuel pump to see if this is really the problem or something else, I hate to spend $50.00 bucks on a new pump and it still will not run. Any advise would be appreciated. Thanks
