Street ported 12a

I am running 200 Main 150 Air compensators with a 24 deg advance at 4000RPM

I just got a Wideband and it seems that I am leaning out at higher rpm like 10.2 AFR

I am thinking that this might be a float level problem.. let me know what you think cause after running 175 main and 160 Air comp, I am lean down low but good at higher RPMs 13.6 - 14.1 but I know I can make more power with a bigget jetting setup...

Any suggestions and advice would be greatly appreceated..

fuel issues such as pressure and incorrectly set float. This is one of the reasons why Im switching to a "fuel log" instead of "fuel pressure regulator" in my next set-up along with holley blue. This will require a return line.

 

10.2 is not lean thats rich. you want to be in the 13's for a N/A
