Welcome to the forum daniel776 and alltruckrage ! :)

daniel776, I would start with alltruckrage's suggestion and clean the carb..

I moved this to the Chinese section where its get seen more...

To add...we think the main jet is clogged/obstructed. :)

AllTruckRage,

When you say you have the same quad is it a *Baja* 90cc quad. They have owners manuals online with schematics (wiring diagrams) inside. Check out the following link:

Baja Motorsports | Owner's Manuals | Assembly Instructions

If you need further help just ask.

Thankyou for the information but I need to know where the wire's go in the plastic plug in the cdi box there's two plug's one two prong and one six prong I need the two prong is two wire's but the six prong is five wire's in with an open slot I need to know where the wire's(w/colors) go corisponding to what slot???Thankyou again!!!

Are you sure the CDI plugs are 2 pin and 6 pin? I've not seen nor heard of a CDI like that. Acording to the Baja wiring diagram and the Baja web site parts section, the CDI has a 2 pin and a 4 pin connector set. Here is a picture of that CDI:

Attachment 20809
The classic color scheme for the above pins is:

Ignition Power: Black with Red Stripe
Kill Switch: Black with White Stripe

Ignition Trigger Pulse: Blue with White Stripe
Ignition Coil: Black with Yellow Stripe
Ground: Green

Many, but not all quads follow this color scheme.

If you really do have a 2 pin and 6 pin CDI can you post a picture of it? Also, what are the wire colors for all the wires going to the CDI?

i cleaned the carb twice and the plug came out black every time i put a new one in should i change the oil

No spark???
 

I have a motoss-90 that somehow has last it's spark I checked and replaced the cdi box but nothing, am I missing somthing all the year's I'v lost spark it's alway's seemed to be the cdi box can someome please point me in the right direction PLEASE !!!!
