TRX 300 fw 2000 wont idle

air filter is brand new any other suggestions as far as takes on cleaning the carb i bought a carb dip solution but cant put plastic or rubber in it and i dont wanna mess with the throttle plate mount

ok ill double check it but first before i tear it apart i was just thinking of taking a little slack out of the throttle cable to at least get it to idle then maybe adjust the pilot screw more lean since its backfiring on decelerating let me know what u think about those steps

ok so here is what happened i got it to idle the throttle stop seems very touchy its ether to high or stalls so i get it to idle and i try setting the pilot screw to 2 1/4 turns out after seating it and i get no change in the rpms i can screw it all the way out or in and no change still misses im getting to my wits end with this carb ive taken it all apart twice to make sure it was as clean as possible im not sure what im doing wrong ive never had this much trouble do you have any other suggestions? is there something im missing? is it would a bad float needle cause this even tho it still has spring to it and the rubber tip seems fine no nics in it or anything

i didnt remove the main throat needle from its case i only pulled it out to clean the jet

is it possible that can stick? should i take it apart to clean it better?

ok thanks that makes sense i only cleaned it not rebuilt im still a young mechanic so i appreciate the help and patients do you know a site where i can get a rebuild kit?

i used a aresal carb cleanerim posative i got all the o-rings out before hand one thing i realized last night when i was working on it the rubber part on the priemer was all crumbled i think i need to rebuild that as well
