Hello everyone, The other day leaving work I stalled at the light. I pushed my scooter into a lot and saw gas leaking from my airbox. I took the seat off and my carburetor was pouring gas out and flowing into the air filter. Finally got the scooter home, changed the carburetor, fuel petcock, and changed the oil (there was gas in it). At this point the tank was nearly empty. Filled it up. Now I can't start it. It's getting fuel and spark but won't start...Feeling really frustrated..Any help would be greatly appreciated.

Also,..The carb I put on was brand new 3 months ago. It was on different scooter that never ran, but sat with gas in it for 3 months without running...Could it be clogged already?

There are no downsides to a good carb clean out once in a while.

Hi,
To further lilpinny's idea, if that carb sat with gas-a-hol in it the insides could be super crudded up. The alcohol and all it's companion chemicals can form waxy globs here and there in your carb. If you decide to clean the carb (highly recommended) be sure to poke and prod ALL the openings with strands of fine copper wire. You might have to sacrifice an old extension cord or something for the stranded wire inside. Carb cleaner alone probably won't clear all the internal blockages so you have to be prepared to poke it a bit. Compressed air canned or otherwise will help a bunch too.
Good luck, Greg
Try to only use alcohol free premium gas in the future that you get from a store that has a dedicated premium only pump so your new gas won't be contaminated with that evil EPA stuff.

Don't just rely on the carb cleaner to do all the work. You will need a bit of compressed air and some fine stranded wire to poke thru any and all holes you can find.
Good luck Greg
Your float valve and seat certainly seem munged up if you were dropping that much gas. So give that a real good look.

An electric guitar string (a 9 guage high E) is usually kept behind the counter at a music shop. They sell singles for a buck. That's a good sized wire that'll fit in all the holes in the Jets and carb.

Yeah, but that sounds like a whole set... All six strings with the low E (42 guage) and the high E (9 guage) and everything in between. You just want to buy the single 9 guage. Shops sell replacement single strings for a buck or so. Usually they are behind the counter and you have to ask for one.

I usually buy the store brand and snag 2 when its on sale. You can never have too much. Be sure to keep it away from the rubber parts they don't like it and get stretched out of shape.

You could have fouled the spark plug with all that liquid fuel coming into the engine. That would not help starting and running.
I would check the float valve/needle valve as suggested. Make sure that the needle is cleaned of all deposits, and the tube that is moves in is also clear. If you don't clean them totally, the needle can stick whenever it gets in the mood, making a mess all over again, and diluting/contaminating your crankcase full of oil(not necessarily, but you have to check for fuel smell and WAAAYY overfull if fuel finds its way in). If you clean the needle, bore and seat completely, it should work for years without problems, but it has to be real clean.
If it ran well prior to the overflowing situation, it's likely the pilot and main jets are clean, along with all the passages. If not, take the time to clean it the first time so you don't have to R&R the carb over and over again.
