Props to rf for his time, im sure alot of people have learned some info.

That's how I started with my 75 - trying to get overall performance from a carb. But I got sick and tired of waiting for stupid thing to warm up early in the morning roaring at 2k RPM for about 5 min! With Delta 40 out in the back I was not making friends with my neighbors. Truck never performed up to my expectations until I switched to EFI - fuel consumption when down and it is now a joy to drive.

Both Chiltons and Hanes do not go into fine system details. Only factory service manuals (FSM) have detailed troubleshooting trees. These are very detailed, but do not (always) list sensor parameters which can be found else where.
