Today i put a 300ex carb. on my '97 300 4x4 and i'm having a few problems i hope i can get some help with. and i did the swap because i don't like having a vaccuum slide and i wanted to have an excelerator pump. and i should also mention i have a full supertrapp exhaust on it, and a power up kit w/ a K&N First my stock cable wouldn't work, the threads on the end of it were to small. so i took a cable off a 250sx and the cable was to short to reach the thumb throttle but i put it on anyway (had to pull on the cable by hand to drive it.) then when i went to put the tank back on, it hit the metal elbow in the cable. so i just let it hit so i could at least test drive it. Then the guy i bought the carb from removed the choke for "better air flow" so i had to pump it like crazy to get it to start. and it runs great and the carb has been jetted. it took off pretty close to normal (maybe a very slight gain) so i went up this hill i can useally take in 3rd and i didn't make it as good as i useally do (started to bog at the top) so i tried it again without the air box lid and no change. so now i'm thinking i'll put all the jets out of my orginal carb in the 300ex carb and see how that is. But basiclly my question is, has anyone done this exact swap before? and what throttle cable did you use? and did it have any power issues? (not enough) and thanks for any help.
