i cant seem to figure it, i ve replaced the cap, rotor, plugs, wires, oil changed and a new fuel filter. it starts up and idles fine then as soon as the choke turns off it runs like poop. i have been able to drive it and it has a hesitation at 2500-3k rpm. timing is around 10 BTDC but when i try to adjust at the distributer it runs worse and stalls out with to much advance. it seems to have be running rich form the black liquid coming out of the tail pipe but the plugs are black around the edges and white on the tip.
