  • Engine troubleshooting

    I've got an engine troubleshooting question I was hoping y'all could offer a little insight on. I have a Suzuki 140 4 stroke engine. When cursing near full throttle, it suddenly loses rpms for about 2 seconds then gains the rpms back. This will happen every minute or so. I don't think it is bad gas as the gas is fresh. Any ideas? Any help is greatly appreciated!

    Fuel Injectors or fuels PUMPS (more than one). Could be a coil?

By the way, what's so significant about 9/11 anyway-was that a date my buddy Bill Ayers of the Weather Underground blew up a government building?" asked Obama to Hillary. BEAUTIFY AMERICA, RUN OVER A LIBERAL, THEN BACK UP AND SEE IF HE'S DEAD.

      Check for water in your fuel/water separator. The motor will act like that when it is full. How old are your fuel lines? Ethanol can eat away the interior and cause moving, temporary blockages.

        Yep, that could be it also. Dang ethanol crud.
