Your scoot hoses look more like this:

Yes, the COIL is the one you took off to check the Spark. So Follow the wire back and you will see a round cylinder and the coil wire goes into it. Take the Rubber Sleeve off the coil and check the connections in back Only two wires make sure they are not loose and or touching it other . If they are loose on the coil get pliers and tighten them up.

so they both go to the petcock, dont suck the one w the fuel filter in it, suck the other?

and thanks ill check that on the coil

[gatekeeper]

I'll leave you in Alley's capable hands cause I've got to go to work. I will check on your progress though as the night progresses. Hang in there and you'll get it. You're doing great!

[straightbangin]

Hahaha. Thanks gatekeeper! Have a good night at work

Yes, What the Vacumm Hose does is it OPENS a Diaphgram inside to allow fuel to flow through the fuel line. And it only works with suction from the engine. So as soon as you shut the engine off the Diaghgram should close like a door and NOT allow anymore fuel to flow to the Carb.

Okay. I unhooked the fuel line at the filter ( just before it ) and a little bit of fuel came out right away and I let it drain into a cup. Probably about a lil less than 1 table spoons of gas. I then unhooked the other one coming from the petcock that lead to the carb. It was coming right from the petcock to the carb ( no T or anything) I sucked it with the little thingee I have and nothing. Figured it may not be enough suction so I used my mouth and sucked as hard as I could and nothing came out of that hose ( it seemed dry ) also when I sucked, nothing more came out of the fuel hose into the cup either. As for the coil, I'm a little confused. I'm going to film the situation and report back in about 10 min.

GREAT!! the damn PETCOCK is bad NO GASOLENA is getting to the carb.
When you suck on the Vacumm hose Fuel should flow out of the PECTCOCK. Was there any gas in the Filter. So that means you need a PETCOCK the carb is not the problem.

You can verify that your scoot will run if it gets gas, you can try and bypass the Petcock and have the FUEL HOSE go directly to Fuel Filter then to the Carb from the Tank. You can take the FUEL Hose connected to the PETCOCK FROM THE TANK and connect that to the FUEL FILTER Directly bypassing the PETCOCK. Fuel should Flow right away and fill up your Fuel Filter
and go to the Carb.

Cool! I just made a video cuz I had a coil question that you would have to see to understand my question. It is uploading now. I'm guessing the hose going from the fuel to the petcock will be the only other hose connected to the petcock and maybe on the top of back of it? Also is a petcock needed? If I can just bypass it and it works do I need a new petcock? Or do I need it and I'm just testing it to see if the scooter will run with the fuel going to it minus the petcock, if that is the case how long can I run it for and or drive it to test it without it flooding my carb. I'm going to assume that w out the petcock it would flood the carb? I have no idea. LOL. I didn't notice if my fuel filter had gas in it. When I pulled the tube off a bit splashed out but not much. I can look again. If I don't need to replace the carb at least I can have an extra one handy to pop in while I'm cleaning the other, etc.. It wasn't horribly expensive and I'm sure someday I'll need another or at least parts from another so I'm still glad I bought it

[Alleyoop]

It is for a test, you can leave it that way and Hope the Carb Float will not allow the Carb bowl to overflow. But if that happens you will know if it is overflowing BYPASSING The Petcock cause you will have gas dripping down onto the Ground. If it runs and stays running then you can test drive the sucker all over the place.

The vid I just made

I just realized I said in the vid that the vac was going into the carb but I meant the manifold

[straightbangin]

Hmmm. I wonder if I were to not bypass it as Im not even sure i can reach where the gas goes from tank to petcock but instead manually filled the fuel line starting at the petcock and just squirted fuel in it. I wonder if like one line full of fuel would get me to drive it around and for how long w out dieing and without overflowing the bowl. Overflowing the bowl or possibly overflowing the bowl sounds bad. Wouldn't that require me to remove the carb to take the bowl out and clean it?

[Alleyoop]

The Coil looks good if you cannot pull on them and they come off easy then they are on pretty good. But if you want you can give them a little squeeze to tighten them up on the connectors. The other part of the coil WIRE is fine that other piece going on the Coil Wire is just for more protection for the wire that should not come off. That all looks good.

But That sucking on that Vacumm Hose and No Gas I THINK WE HAVE FOUND THE PROBLEMO.

So If you can bypass the Petcock with the Fuel Line and connect it to the Fuel Filter that would prove it. I am hoping that the Fuel Filter can reach the HOSE from the Tank that goes on the Petcock, So that you can take the FUEL LINE coming from the tank on the PETCOCK and connect it to the Fuel Filter.

Ok I will try. Do I keep the vacuum hose hooked up to the petcock? I'm going out to check out the hose situation. Thanks for the feedback on the coil too

[Alleyoop]

Yes you can leave the vacumm connected to the petcock. You can also get a VALVE CUTOFF and use that instead of the Petcock. But then you would have to remember to shut it off and turning it on. Usually MOPEDS use a Shutoff valve and the carb does not overflow UNLESS of course there is something wrong with the FLOAT inside the BOWL and not shutting off the incoming fuel.

So if you can bypass the PETCOCK and no flooding you can order the PETCOCK and still be able to use the scoot while you wait for the PETCOCK.
