am running a 48 dellorto dhla on my stock port w/exhaust on my 85 se and cant figure out why its running lean when i jump on it and rich when its idling. I just had a 40 idf on it and did the same thing and was thinking it was the floats, the idf had a crack in the float the plastic piece so i change to the 48 dhla and is doing the same but have checked everything on it before putting it on. The carb is a set-up of racing beats and havent chneged anything on it Can someone help me please. The reason i know is cuz i havea auto meter gauge. ty

Sounds like it just needs to be properly jetted, need a smaller idle jet and a bigger main.

On the other hand, using a regular O2 sensor / air fuel meter isnt going to be a very accurate way to gauge rich/lean.
