i believe they are in the bowl on the bottom of the carb... loosen the screws that hold the carb in place turn it on its side (gas off)... undo the screws on the bowl... then u will see it...

 

unless you are very experienced with carbs i would not recommend trying to fix this yourself. it could damage you engine or your carb itself.

 

Take the carb off. Be careful with the rubber piece between the carb and the jug, if it's too old it will break. Take the bowl off the carb, flip the carb over. There it is. Looks like a little gold slotted screw. Should say "145" on it. If it's stock you'll have a little round piece of plastic under the jet - my dynojet kit said to remove this. Make sure you keep ALL other hardware intact. Unscrew the old, screw in the new. That simple. I believe there is a washer/spacer under the jet, leave it on. The only other thing would be your needle (slides in & out of the jet to allow fuel flow). I'm pretty sure the one that came with my kit had a smaller than stock diameter - you may need this too, not sure.

 

how old is your warrior , i have a older one that was stock and in the late 90's they did slightly improve the performance on them just make sure your warrior is tuned properly .
