[Mgs] HIF Carb Hesitation

[John DiFede]

For starters I would check gas filter, air filters, ignition wires, distributor cap and rotor and fuel mixture by lifting each carb piston slightly while the car is idling.  You may have a bad ignition wire that is shorting to ground.  If you can run the car in the dark, race the engine slightly and look for arching / sparking between wires or to the engine block.
