I'm at my wits end! I thought I had it figured out. new battery/new fuel pump/new plugs/new coil/new condenser/fresh gas/clean carburetor and he starts quickly and idles for days!!! but when I drive more than a mile, he acts like he's running out of fuel. Give him a minute and with full choke starts right up. as you ease the choke back, he shuts down. battery is hot and tank is full of fuel. ANYBODY?
