Other Homework Help

I have a 76′ dodge b-200 360,auto with a/c. The engine “surges” whenever I go up a hill in 2nd or 3rd gear and sometimes on fairly level ground. I’ve replaced the vacuum hoses,cleaned plugs,rebuilt the carb (holley 2530 2 bbl.),checked the timing (even tried both advancing and retarding. neither worked). When it happens it’s hard to tell whether i’m flooding or starving,but when I let off the gas (almost all the way) it smooths out. PLEASE HELP. Thanks,Bill.
