  • More Fuel Problems

    So the diagnosis of the motor has been cleared up. I messed with the carbs some more, used a better cleaner, and believe it or not actually cleaned and spray out with a hose and let dry. This must have worked great because I put it all back together and it fired up and ran real good on the hose (being fed fuel on a portable tank with fresh gas).

    So I drop the boat in the water and idle away with the motor hooked up to the boats fuel tank with 20 gallons of fresh gas (I do know the tank when I drained all the old gas out of it was pretty dirty, but I wasn't expecting there to be any issues after draining/pumping the old dirty fuel out.

    Needless to say. The motor idled away from the ramp nicely, ran for about 6 or 7 minutes idling out the channel and then could open it up. Opened up nicely got up on plane, planed out now crusing along around 4000 RPM's then it just slowly lost RPM's and died out. Was able to get it fired back up 2 or 3 times, but then it just died. After that. NOTHING.

    Switch out to the portable tank. Still cant get it started. Will investigate more tomorrow. I am noticing some pretty yucky fuel coming out of the water seperator both times that I've run the boat with the boats tank.

    I guess my next step to eliminate any motor issues is to ONLY run on the portable tank next trip ( after I get it started again that is ). If it will run all day on the portable tank, then obviously something is happening with the fuel (that is only a week old, but was put in a dirty tank) in the boats tank.

    Any suggestions guys? I'm guessing Im going to have to pop those carbs back off huh?

    Your on right track

    Fuel delivery or the fuel it's self is problem. I posted suggestions already and wont go over those items. Hopefully you did some reading up. If your spraying harsh cleaners in the rubber fuel lines id suggest just getting new ones if there that dirty. Rubber may come apart into the carb and wamo.

      Not spraying anything harsh in the rubber or plastic for that matter. All the lines are good. I blew compressed air through them no problems. The carbs were good too after a thorough cleaning. Im thinking my problem now is a nasty fuel tank. Even after draining the tank, and adding 20+ gallons of fresh gas, it still seems to be plugging things up.

      I guess one option to further evaluate would be to just keep running off the portable tank that I know has good fresh clean gas in it. IF it continues to run on that, then obviously I have to address this main fuel tank somehow.
