Just traded for a 90cc kids quad, not sure of the brand still trying to figure out. starts but dies after a few seconds. when i put my hand partialy over carb it runs good and stays running! can someone help or give me ideas! also posting a pic and if anyone knows what it is or has any idea let me know. Thanks

 

Welcome to the forum bdt

Your carb needs to be cleaned..

 

i already took it apart and every thing looks good, cleaned with carb cleaner. seems like its something with the air cleaner assembly. not sure at all

 

Could you see light thru the jets?

what is the fuel screw set at?

 

The main jet was the only one i saw. it was clean and could see light through it. i have the idle screw set about 3turns out. seem to rn the best there. I am still trying to get a picture of the quad on there.

 

The main jet is the big jet of the 2(hardest to plug and easiest to clean).. Id take a look at the pilot jet and the holes in the side of the main jet holder..

 

ok i will check them out. i will let you know. thanks

 

Your welcome.. and while youve got it apart.. spray carb cleaner in the hole where the pilot jet goes and where the fuel screw goes.. both are thru passages and are the smallest holes in the carb..

 

Ok, Took carb apart again and cleaned everything, i found the other jet and cleaned it. every thing seems to be open and clean. wheni put it back on it does the same thing. with air cleaner on it wont even start i have to take it off and put my hand in front of it then starts and runs good. Is it a fuel air mixture problem?

 

Weird.. are the gaskets and or o-rings good on the carb manifold?
