anyone good on carburetors?
 

i have a 90 prelude and when first started in the morning, idles very high, then after a little while, idles extremely low, almost to stalling, then after about 15 minutes of driving, its fine, i dont have to pump the gas or anything, but i can smell like oild burning or something....its been worked on many times, i dotn think its just an "idle adjustment". Anyone that has a lot of knowledge about this please give me your opinion. If you really dont know a lot please dont waste your time feeding me BS
