Cag bogs when throttle is fully open

Everything seems 2 b running good until i open the throttle all the way, at that point cag just stalls out. Good news is it starts right back up on first pull so i don't think i have over heating issues. Can someone point me in right direction?

Try putting it to half choke, and clean the carb

man thats about the most ghetto thing i have ever heard of. dont listen to this guy. if it runs for a few seconds and dies its running lean. you need to turn the small flat head screw qithout the spring onit about 1 full turn counterclockwise. if that helps go from there. the reason it is dying is cause its just burning all the fuwl in the bowl and when thats gone it isnt getting enough fuel through the jets to keep it running.

that screw would be the idol screw, that only causes the bike to run richer at idle, not WOT, u need to re jet, u have to buy a jet kit from some online store and use a bigger jet

but he should be able to fix it without buying any new part right?

try cleaning out your carb.
and make sure all screws on your engine and everything is tight.
and what color is your spark plug? (unscrew it and check the color of the side that goes into the engine).

well what i MENT to say was put it at half choke and try riding it, if it stops bogging then you know that your carb needs cleaning,

look little one, learn a lesson form someone that actually knows about motors. the screw with the spring is your ****ing idle screw, the one next to it without the spring is your sir fuel screw.

hate to rain on your parade but stock cag carbs dont have an air/fuel mixture screw. they just have an idle screw.

you control the richness by bending forks =]

seriuosly. my buddy had a cat eye and his had a air fuel screw. guess the cag motors are different

yeah cateyes have it because they have 49cc piston port motors.
they have different carbs. cags are reed inducted 47cc engines. smaller carbs

oh ok. thanks for the info.

will the 49cc x1 piston port engine's carb bolt directly to a cag engine? Or would you need a different intake mani?

Wow this simple post is full of all sorts of misinformation!

Standard Cags only have one external adjustment and that is the idle stop screw! Yes, your bike is running too lean and it does need to be adjusted.

Do not bend the float forks, that does absolutely nothing for your mixture!

You need to adjust your mixture and there are only two ways that can be done: 1. Try adjusting your needle position (on the throttle slide) up one c-clip groove. 2. replace the main jet with one or two sizes up (this will require that you purchase a jet pack).

Do a search on how to do either. Debris can also cause a similat lean condition, but, it is usually a jet size issue.

Good luck

The cags half mixture screws but it isnt technically a screw it is in the throttle needle there is notches on the needle and you move the c clip on the needle down more notches to make the mixture richer and there is five notches on the needle. O and for the bogging down thing my bike was doing the same thing on my cag and I cleaned out the carb and it was alot better.

Yo Fellaz- thanks 4 all the info!!! Been out of town and have had no comp access- got back and found this great disscussion on (as pointed out) a simple issue. But this is why i love PBP-real riders who know how 2 discuss this sh*t. What i'm not sure of is on the throttle needle- should i move it up or down, i think there were 2 diff answers. And just so u know- couple days after i posted about boggin out- i started my lil beast up and he ran 4 about 2 minutes- died and has yet 2 start back up. What really confussed me was that the fuel filter bowl filled up with gas, and normally there is only gas in the bottom corner of the bowl. Should i still be lookin 2 the jet?

if it bogs at full throttle wouldnt that mean it is running too rich and the engine is flooding? if it was too lean it would take off but then die from lack of fuel.

Check your plug. If it's white-ish, you're running too lean, and move the clip down a notch. If it's dark or black, you're running too rich - move the clip up a notch.

Mine bogged down at full throttle, but it was because not enough gas was flowing into the carburetor - once I rejetted with a 72, it seemed to work a lot better. I may stil be running a bit rich, though - haven't checked the plug yet.

OPh, and as for bending your float forks down, the only thing that acccomplishes is sealing the overflow a little sooner. As the float rises, it presses against the forks, driving the float needle up into its tube, and shuts off the flow of gas. Simple, eh?

I have a pocket dirt bike with a cag engine and when i start it up it goes by itself and when I am riding it and not even throttling it it will go at about 5mph. and when I startto throttle it it dies. So what could this be??? and how many turns out should the idle screw be. -thanks

CrazyJ you have over 1300 posts and you haven't read one of the numerous posts about broken clutch springs, or, how to adjust the carb on a Cag?

You need new clutch springs first off! Second, the idle screw does not have a setting. It is simply an adjustable stop screw for the throttle slide which allows you to set the idle speed of the engine. Once the engine is running, turn it in a bit at a time until the idle speed is at your liking. If you have adjusted the idle speed too high, you may be casuing the clutch to engage which may also account for the clutch issues.
