I'm just wondering about the necessity of the counterweight behind the fuel pump eccentric. The Eickman book seems to suggest that the counterweight was used in early Y-Blocks, but dropped in later years(?). Since this is a  C2AE block with a Rollmaster timing chain, should I use it or not? I can't see how it could hurt anything by having it in there.

Thanks,
