I have a 125 wet shot on a 355 motor. The compression is 11:1 with a cc305 cam and P&P stock heads. After about 3-4 runs on the bottle I foul some plugs and it will not rev over 5000 rpms on the bottle. I am using the recommended jettings from the manufacturer. What can I do to fix this?

Thanks guys.

 

First thing you can do is lean it out. The factory jets are usually fat,try 1 smaller on the fuel jet.might have to go 2.

Gonna take some tuning,just see what the car likes.
