fuel problem

I have a simplicity 1732. I t works great but I have had problems with what I think is water in fuel bowl. I use non-ethanol fuel, store the gas and machine in a heated garage. It can work fine for several uses then cut out. I add a little ISP alcohol to pass the water when this happens but I cannot figure out why this happens. It has been to the local shop many times and of course, it run just fine for them... Has anyone else had a similar experience?

Run it out of fuel, use stabilizer, Sea Foam.

Next time when you have the problem, try loosening the fuel cap and see if it solves the problem. You might have a cap that is marginal on venting.

OMG, that seemed to work! Pretty amazing and simple solution that three mechanics could not think of?


Thanks!

I've had it happen to me. It's a quick and easy way to diagnose the problem. I might need to make a service call to Sun Valley.

CO, very interesting solution. I would have thought it was just the opposite: a loose venting gas cap could allow moisture from a damp garage into the fuel tank. Why does loosening a poor venting cap relieve a water issue in the tank?

Sun Valley-- beautiful country out there. When I was little, my dad took my family there many summers for vacation. I miss the fishing and Mountain Biking and I would love to go skiing there sometime.

I'm having a similar issue. I have a 2008 P1732 Sig Pro. It'll run for about 20 minutes and then shutoff. starts right back up with electric start, but never by pull start. Very frustrating.

If it runs ok with the fuel cap loose, then I don't think you are having any moisture issues. Normally the cap allows air (but not water) to enter the tank as the fuel level goes down. If the vent doesn't work, it creates a vacuum in the tank and the fuel is unable to flow so your engine starts cutting out.

Its either time to buy a new fuel cap or make your own vent in the cap. You can do that with the smallest sewing needle you can find. Hold the needle with vice grip pliers and heat with a propane torch until red hot. Make sure the fuel cap has been wiped dry and allowed to air dry. Use the needle to melt a hole in the center of the cap until the needle tip just barely exits (have the needle pass from the inside surface of the cap to the outside surface of the cap). That gives you the smallest hole possible. Some people have concerns with moisture getting in the tank. All I can say is that I used my cap for 2.5 years without a problem.
