the carb is letting to much fuel into the motor and causing it to flood. i know there is something wrong with the carb cause i put a carb off of my other 250x and it strated right up. i'm thinking that it has something to do with the float. how can i fix this.

 

your best of just getting a new carb kit and putting all new stuff into it

 

ya i was thinking of doing that since it is only like $20. are the carbs the same from 87-92 cause the kit i looked at said it only fit 91-92?

 

The 91 92 uses a smaller main jet(122 vs 125), and a bigger pilot jet(38 vs 35)....than the other years of 250x. Thats all thats different in the kit. You can also use a 300ex kit, which is 125/38.
Id try to fix it with out using a kit. The float has a needle/seat which closes and opens to allow gas to enter the float bowl. Most likely this junction has a bit of grit or crud , which stops the closing. Start by just doing a good carb clean...remove the jets, and clean out the needle and seat area good. That should fix it..for free (except your labor)

 

ya i'll probably take it apart and clean it really good. thanks
