Let's hear what engine, carb, and jet size everyone is using. I just want to know how far off I am on my 70ss with a 28mm keihn with. 50 pilot, and 152 main. Screw at 1 and 5/8 out.

I believe you are running way too rich. On our cr 85 stroker motor we ended up with a 28 keihin d-slide with 142 main and 42 pilot. It idled best with a 40 pilot but Hetrick recommended bumping it up . Look at my post for cr 85 help and you will find all kinds of advice for jetting. Rounds slides were even leaner.
