Carb advice?

The Eddy 1406 carb is an economy carby. The better carb is the 1405 which runs richer for modified street engines. I had the problem where the car surged and pinged at light to medium throttle. This indicated the carby was very lean. This was fixed by jetting up the primaries to step #19 from the carb manual and I also jetted up on e step in the secondaries aswell. You need to download the manual to see what I am talking about. The 600 is fantastic down low. Buy the jetting kit for this model and retune the carby under instruction of the manual. Don't put a bigger carb on the car. You will end up back to the 600.
