ive been an auto mechanic for 20 years and this thing is driving me nuts . i thought KIA's were POS cars . I think im going to bring my air hammer home and finish this motor once and for all. cheap chinease pos . and the ebayer i bought it from tell me to come here and post the question instead of helping me directly. i have never had such a terrable ebay experance in my life. i think i would have been happier if i spent the $230 and never recieved this POS .
wish i could resolve this issue with "dacscommm" but hes just going to get horrable feedback

Last person to have these symptoms had the throttle cable adjusted wrong. Not enough slack INSIDE the carb. It was too tight and the needle couldn't seat. Just a guess

could also be a leak at the manifold connection of the carb that is pretty common but im not sure it would cause it to race it might. Most likely the throttle cable i think

Hi Autodoctor, first welcome to the forum and secondly sorry to hear of your bad experience and glad your ok. The first thing I would check is the idle screw on your carb, it should be 3-4 full turns out from tight. Always start with the simplist fix first. Have a great ride...Kelly

Are you sure you have your carb assembled correctly ? Does the slide go up and down ?

 

[Norman]

no goodnic
Is telling you the straight stuff you could even start the idle needle all the way in, I will bet it will stay running then. You can then stop and back it out to lower the rpms. By the way that is an idle adjustment there is no idle mixture screw.
I hope you don't have anymore wreaks or trips to the hospital that's not fun.
Be careful.

Any air leaks ? Have you checked for air leaks? Do you have an inline filter between the tank and carb? When you installed the new fuel line, did you flush out the new fuel line before hooking it to the carb? You may have some particles in your carb restricting fuel flow. Did you remove the screw from the top of the spark plug? Is the carb pushed all the way on? What position is your C clip? Middle, top? Bottom? Where? Let us know. Thanks..

3/4 or more? Sounds like it's too rich.

Set the needle at the second from the top.

Also, when setting the IDLE SCREW you can turn it in with your fingers and feel when it touches the slide....after you get there, start it up and turn the screw in (clockwise) a little (1/4 turn) each time until the idle is right.

Keep us posted.

BTW, how'd you wreck it?

If you remember tell us how you smacked your noggin.

does any body offer AMERICAN REPLACEMENT PARTS FOR THESE THINGS!!!
ok i took the carb apart.
1st. off the idle screw when it was turned all the way tight DID NOT even go into the slider housing . upon further examantion the pilot tip was mushroom shaped . a little polish/grinding i was able to adjust the slider with the screw. however the screw is not straight its bent.
2nd the carb was set up on the 2nd from top clip. so i put it to the very top clip
and it did idle alittle bit and it actually started quicker but that was short lived
i would like to get a quaility carb/ plug and coil for this beast . i just hope the motors are made decent and hold up for a 1000 miles or so other wise i just wasted $250

 

[Bikeguy Joe]

250!?! WOW, where'd you get that one? I paid well under 200 WITH shipping for all of mine.

People have fitted other carbs quite successfully- Walbro, Mikuni and Del'Orto's.

B5HS NGK plugs work great, as for the coil, there are folks working on that as we speak.

I wish you hadn't mentioned that about the switching of the carbs. I have at least one perfectly good carb from the weed eater experiment. I will have that on my mind all day now.

I noticed that the price of the kits is creeping up. I bought mine for a 142 and now I see the average looks like 175. Those prices include shipping. My son in law would be the perfect kit buyer. He would believe the most expensive kit is the best one.

 

[Bikeguy Joe]

Yeah, I've seen 'em go for more than they could just be ordered for from the dax website!

I got all mine pretty cheap (under 150 plus shipping) one sold for 110!!!!!

But yes, I think since gas prices and popularity of these is creeping up, so is the price.
