i have been looking all over got the k&N jetting kit for the 1992-2003 300ex's, changed the needle, but where is the main jet? anyone have a picture showing it or can describe it the instructinos dont show it

 

up

 

Hold the carb upside down. There are four phillips head screws holding the float bowl on. Remove the screws and the bowl. In the bowl is your main jet, and other stuff. The main jet is made of brass and it takes, I believe, a 6 or 8mm wrench to remove it. Take it out and put your new one in the same way just backwards. Make sure to get everything the way you found it or you'll have troubles. GOOD-LUCK

 

k found that... only problem now is got 3 stripped screws.... right when i flipped it over they where stripped any clues how to get them out?

and i tryed runnign my quad w/o the main jet chagned... chagned the needle though and second gear full throttle felt like nothing.... than 3rd would even chug more and wouldnt excellerate, any clue what that is... than after that it wouldnt even start

 

That happened to me also. I used a small pair of vise-grips and was able to get um out. If that works get new screws.

 

acually there is a MUCH easyer way! Just take the drain screw off and its right there. Dont bother with take the thing all apart. And if you really want to make it easy then all you have to do next time is to loosen the screws on the intake boots and twist the carb so that its almost side ways. Then take the drain screw off and change it. simple! Dont forget to turn your gas off. lol
