Re: Cag leaking gas from overflow tube HELP

Please try using the Yellow Search button. If you had searched on "gas leak" you would have found the info below. This happens to most Cags. The quick fix is to bend the float arms down a bit. Good luck. -Fritz


"Is the fuel coming out of your drain tube? If so you have a stuck or clogged fuel float in the fuel bowl. If that's the case it's real easy to fix and I think every Cag owner has experienced this problem. Turn off the fuel petc0ck. Take the 2 screws on the bottom of the carb off and slowly pull the bowl off being careful not to tear the gasket. Once off you'll see a white plastic donut (the float) and a 2-prong metal arm hinged to the carb. When that Fuel bowl is full of fuel the float with rise and put pressure on the Float Arm. That float arm is attached to a valve that opens and closes allowing fuel in. Look under the float arm at the valve and see if there is any debris in the valve. Sometimes plastic shavings or pieces of gasket get clogged in here. Blow on it a few times just to make sure and move the arm with your finger to ensure it moves freely. Now, take the float arm and bend it ever so slightly down away from the top of the carb. This will allow the float to apply more pressure on the valve. Now put the float back in the bowl, flat side up, and reattach the bowl to the carb. Make sure the screws are tight enough that the gasket is sealed but don't over tighten b/c the carb is soft aluminum. Now turn on the petc0ck and you should be leak free!"

Unhappy Re: Cag leaking gas from overflow tube HELP

well i didnt want to be a pain in the but so i just said it would work ect. you were right though i think its leaking becuse the float or what ever.

but im only 14 and i got this bike as a big gift and i have noone else to help me out on it. can you please post a vid of how to fix this problem or find a vid for me pleeease.

i looked up tutorials for -bending the float arm or w/e back down- but cant find any.

Re: Cag leaking gas from overflow tube HELP

Kid, we've all tried to help you, but you've got to try somethings for yourself. You need to learn by doing, and you can't really mess things up and make them worse. The tutorial is good, just take off the bottom of the carb and remove the float. The part in the pic is the float arm or as some call it the fork. Just bend the two arms down a bit, like a 1/16 of an inch. You don't even have to remove the float arm to bend it.

Talking Re: Cag leaking gas from overflow tube HELP

All, i have to say is wow... i was kinda worried id screw something up but i went out there fixed it in prob under 5 minutes just had to bend the arms down =D.

thanks for the encouragement and im glad i went out there to fix it.

but i have another question =/...

this cagllari is about 4 months old... i did proper oil mix ect. -for the break in- and stuff and followed all the directions untill break in was over.

however whenever i give the bike more then 35% gas it starts shaking and the muffler is rumbling terribly then if you give it even more after about 50% it just stalls out. i AM using proper gas / oil mix and did all the break in stuff. it goes about 25-28 -next to my brothers car-. its stock also.

i was told before that as a -stock- cag i am very lucky to have it going 25+ but why is it that if i give it more then 35% throttle it stalls? i feel if i could give it more it would be going like 40 lol.


MY SECOND QUESTION IS -before im completely done =P.. is..

there is a -black cover- so to say.. on the back of the carb by the tire ok.
i had a X7 Bullet before and when i took this -black cover- off of that bike it went ALOT faster almost as if it was a speed govener.

but i was told at the shop its just that when you take the cover off there is pros and cons about the risks.

by taking it off you let alot more air in meaning -IN MOST cases- more power. i want to know if its the same deal with the cag? he said its risky becuse if the cover is off then theres a chance of dirt rocks road debree ect. getting clogged in there =/. but im wondering if i take it off will it get more air and go alot faster like my x7 bullet did???

thanks for all the help to this point and im sorry for being a pest before this will be my last trip here. -hopefully-

ty all i really really do appreciate this ALOT. ty

Re: Cag leaking gas from overflow tube HELP

take the black box off and just use a panty hose for a air filter, but buy one of these, way better than that box

af24x - Pocketbike Angle Filter Kit

then select the color u want, and where it says velocity stack, choose the second one, it says 47cc stock carb

Re: Cag leaking gas from overflow tube HELP

If you've just pulled the bowl off your carb, and are looking at it, there should be a fork thing inside. That's the piece that needs to have the arms bent down a little - not much, maybe 1/8". Your float comes up against these arms, and presses them upwards. The needle on top of those arms gets pushed upwards into its tube, and stops the flow of gas.

Re: Cag leaking gas from overflow tube HELP

RcaerKidd: that "black cover" between the carburetor and the rear tire is your air cleaner. It protects the mouth of the carburetor so that nothing gets in it like dirt, dust, rocks, etc. Try Juanitoboy's trick with the pantyhose, or if you feel you HAVE to have something back there, try MY trick with the Altoids box (ya gotta work on it some, but it's kinda cool and goofy and IT WORKS!)

Jazer: sounds like your throttle is sticking a little.

Re: Cag leaking gas from overflow tube HELP

Probably a kink in the cable someplace, or just sticking - try shooting a little WD-40 down inside the cable housing.

Re: Cag leaking gas from overflow tube HELP

Actually, it's best to mix it OUTSIDE the tank in a mixing bottle or a 1 gallon gas can. I get my bottles of 2-stroke oil (I run 32:1) from my local auto parts store, pour one of those into an empty gallon gas can, then take the can to the pumps and fill it up. Hasn't failed me yet....

Hey, it's okay - the stupidest question is the one you didn't ask ....
