    big red carb problem....

    so i went to swap the carb off of my fourtrax 250 to my big red, after i swapped i realized the throttle cable was longer on the fourtrax to accommodate for the longer frame. no biggie, so i swapped the big red throttle cable into the fourtrax carb, my idle was insanely high, the cable was now too short thus holding the throttle lever up. i spent 2 hours looking for how it could be too short, the carbs appear to be exactly the same, is there any tricks to installing a throttle cable i should be aware of? is it possible when i screwed in the throttle cable housing ends i twisted the cable in the housing and made it scrunch up and become shorter?

    Check where the cable screws into the top of the carb. There is a jam nut on it to adjust the free play out of the cable. Screwing the cable all the way into the carb will take tension off the wire. I didn't put the wire into the throttle arm till i screwed the cable in to keep the wire from twisting. I also held the cable and spun the carb onto it so i didn't twist the cable. Hope you understand what i'm trying to say, i'm not very good at describing things.
