Scooter is broken? By curiousgeorge (Read 1,640 times)

Hey guys, so my scooter because well i was being an idiot fell over today. I was holding it and it starting tipping so i held on for as long as i could but had to drop it around 8 inches above the ground. I picked it up, only minor scratches, can't even notice unless you are looking for them. But the engine was flooded so i waited half an hour and it still wouldn't start, finally after 45 minutes it started and idled, but as soon as i used the throttle it would just make putting noises out the exhaust . Now it barely starts, take multiple attempts to get it to start, and it will only idle. every time you give it any amount of gas it just makes putting noise out the exhaust. I check the air filter and cleaned it, checked the spark plug and cleaned it, checked the hoses they seemed fine. I also cleaned the carb and fuel filter. Idk what is wrong here guys and I am really frustrated at myself for letting it drop and now having this happen. Does anyone know what this is?

Do you have a pollution vapor canister? If so you probably flooded it and lost the tank venting. Try loosening the gas cap and see if that makes a difference.

Laying a scooter down should not hurt anything. In fact I purposely lay my 150 down on its left side when setting the exhaust valve as it is a lot easier to reach from the bottom. You may have a charcoal canister That is flooded. Same thing can happen if you over fill the gas tank on some scooters. I removed that from mine when I got it.

[curiousgeorge]

I tried loosening and even removing the gas cap and that did nothing, and how to I see if my charcoal is,flooded and how do I un flood it? I made a video of me starting up the scooter and giving it gas so you could hear what it sounds like when I give it some throttle.



I hope that video helps you hear what it is doing.

That Video Link does not show any scoot.

[curiousgeorge]

What does it show alleyoop?

Alleyoop, I modified the link to the correct one, it should work now if you open it up to check it out.

[sprocket]

The float bowl is probably empty, perhaps vapour locked...you need to check if you have gas in it, open the drain and check...when you crank the nineyou should get gas flow from the drain...

[curiousgeorge]

Sprocket, that is not the problem, I checked and there is a flow of gas so any other ideas? I am really at a loss for what is wrong. I think I might just pay a scooter repair shop :/

Now the Video works, the carb has gas and is getting gas. Get your screwdriver ready start it up and let it warm up Then find the FUEL RATIO MIXTURE screw.
1.FIRST turn it COUNTER CLOCKWISE 1/4 and wait for 10 seconds or so to allow the motor to catch up with the new sitting.
A. Listen for the IDLE IF IT GOES UP repeat 1, UNTIL on the last 1/4 counter clockwise it does nothing or the IDLE GOES DOWN-- THEN turn the screw 1/8 Clockwise.

**** IF TURNING IT COUNTER CLOCKWISE the IDLE GOES DOWN RIGHT AWAY.. Then DO THE SAME THING BUT CLOCKWISE***

The appears to be Either To much FUEL or NOT ENOUGH. It is hard to tell which one it is when this happens right off IDLE.

DO YOU KNOW WHERE THE FUEL RATIO SCREW IS ON THE CARB?? If not put up a picture of your carb And I will show you.

ok alleyoop i believe i know where it is, it is in the standard position that most are in whenever i see a picture showing how to adjust it......but, the problem is there is no screw, it is just like a flat copper disk. Like there is something over the screw or something, almost as if someone sealed it off?

[curiousgeorge]

ok so in this picture where the air/fuel ratio adjustment screw is, on my carburetor in that exact spot isn't a screw, there is a flat copper cap basically. it is just a smooth cooper circle where the screw should be. is this bad?

[curiousgeorge]

Also when my key is turned in the ignition so the moped has power, the signals blink fine but the front headlight doesn't working unless I do the passing switch for the high beams. The low beams or high beams won't work on a constant setting. Except if I hold the rear break on. If I hold the rear break in then the headlight works. Now if I turn the engine on the same thing happens, except the turn signals turn into a solid instead of blinks to indicate a turn. What happend to the wiring?

[Moat]

curiousgeorge - don't worry about playing around with the idle mixture screw. The idle mixture setting has nothing to do with the bike's current problem - which you describe as idling fine, but bogs on accepting any throttle. The scooter falling over wouldn't suddenly change the idle mixture screw's setting.

As the first few posters have mentioned, it's probably a flooded EVAP charcoal canister (or related plumbing/valving) - try fully clamping off all of the hoses leading to/from the canister, and remove the gas cap... then see how it runs.

OK - wiring/bad ground connection/loose connectors could be the issue with poor running, as well. Something might have pulled loose when the bike was dropped. Start at making sure the battery posts' screws are tight. Then look at all ground cables that connect to the frame or engine. Then just go around checking that all harness connector blocks are seated snugly, fuse(s) are healthy and making a good connection, etc... (especially ignition wiring - CDI module, coil, pickup coil wiring connections). Look closely at the R/H hand kill switch and - especially, if your scoot has one - the sidestand kill switch and wiring. You might want to bypass those in order to check, if you get that far.
