    Problems starting Honda Scoopy 50cc

    Hi guys,

    not sure if anyone can help, but I have a Honda Scoopy 50cc scooter that has only done 500kms, but has been sitting gathering dust for a year or so. I have charged the battery, changed the spark plug and added newer fuel, but unless I stick fuel directly into the carby, it wont crank over.

    I'm thinking I'm going to have to drain all the fuel and get some premium and try that.

    Does anyone have any suggestions? Is there something I might be missing?

     drain it. that fuel (a year old) would be really off by now.

    There is a fuel shutoff valve on the bottom of the tank that stops fuel flow when the engine is not running.

     At a guess while the scooter was in storage the fuel evaporated from the carby and fuel lines.  Now you are trying to start it again the fuel is slowly flowing down to the carby but not fast enough to fill the carby and start the engine.

    You are probably close to starting if you cranked it for about 1 minute. 

    Three posibilities, keep cranking, keep adding fuel to the inlet to keep it kicking over until the carby gets fuel or take the vacuum line off the carby and suck on it for a while to let the fuel flow down to the carby.

    Either way you should be close to it starting assuming its just the fuel shortage in the carby.

    Is that safe to breathe in petrol fumes? I had to transfer petrol to/from a container by sucking thru a tube for several seconds I felt "bad" afterwards inhaling the fumes.

    The scoopy runs a #35 pilot jet. Jets this small get blocked real easy. Petrol over time when left standing turns to goo and the goo will be blocking the pilot jet and stopping the scooter from running. Take the carb off strip it down and clean it out. It's never going to run right until you do this.

    well i found the screw to drain the carby, did that.

    Pulled the whole carby off and took off the top, pulled out the spring and needle and sprayed the whole thing liberally with carby cleaner.

    changed the spark plug, refilled the coolant (as it all drained when i took the carby off). Also drained the tank and put in fresh fuel.

    Still no joy!

    It's like it wants to kick over, but just cant get there. It will splutter for about a second, then nothing. Any other ideas?

    You have to take the bottom of the carb off, remove all the jets and clean them out properly. Having a blast of carb clean squirted in the top wont do very much at all.
