i 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. ty

 

How do you know it's going rich and lean?

 

Exactly!!! RB dellorto's run very rich.

 

i am running a gauge on it to see what its doing

 

is it an arco burger guage?

i wish i could rob but your always busy and i understand mexico and how is fido and that hot chick debbie

 

are you sure the carb was originally setup for a stock 6 port 13b?

 

Pull the jets out and compare them to the gruntled web site to see if you still have the original RB jets in there.

yes i do have the original i checked them all of racing beats setup

 

If you feel that its running lean, then use a differnet emulsion tube.

 

If engine bogs when you floor it, at a low rpm, that is common with 2bbl carbs and rotary. Smaller chokes help out but reduce airflow potential. 4bbl helps too

With my dellorto's, I am used to it.

Also verify fuel pressure with a good gauge. That can be the root of many problems.
