quick check list when ITS just not running correctly
--------------------------------------------------------------------------------
If you were local it would be easy to diagnose, but lets start with the basics

whats the COMPRESSION TEST reading for each cylinder?
HOW did you adjust the valves?
ARE ALL THE FUSES GOOD?
first check your shop manual for the fuse and fuse able link locations
fuses are located in several locations and fuse-able links near the battery
CAN you post detailed pictures of EACH spark plug?
whats your FUEL PRESSURE?(does it stay steady as the rpms build?)
HAVE you verified the throttle blades in the carb and linkage fully open?
how are the carb FLOATS SET?
what air filter SIZE and is it clean?
whats the TOTAL IGNITION ADVANCE?
whats the VACUUM READ AT IDLE?
whats the VOLTAGE at the COIL?
AT WHAT rpm does the advance reach MAX advance?
WHAT is the exhaust back pressure reading? (IDLE and 4000rpm under load)
HOW did you determine true TDC or did you just assume the timing tab and damper are correct?
What color is the ignition spark?
what is YOUR OHMS reading on the plug wires?
whats your spark plug gap?
CARB JETS? METERING RODS?
HAVE you REPLACED the cap and ROTOR?
ANY indication of a MISS or BOG?
HAVE you tried a DIFFERENT CARB?
have YOU verified EACH cylinder is firing?
have you VERIFIED the FIRING ORDER IS CORRECT?
HAVE you VERIFIED the LASH/PRELOAD on the rockers RECENTLY, and are you sure the cam is not worn?
are you SURE the trans fluid and rear differential are filled to the correct levels?
whats the engine temp after it warms up?
whats the trans fluid temp?
AND even if its a carb,equipped engine or if its injected ,ID add about 8 OZ of marvel mystery oil and two cans of separate and different brands of injector cleaner to my first full tank of fuel to dissolve crud in the lines and fuel tank, Id replace the fuel and air filters, and do a basic tune up , plugs,set the timing check for vacuum leaks, meter the plug wires with a V.O.M. and replace defective ones, verify the plug gap,you might be surprised at the number of times that helps.
