it was running fine, but then turned a corner while driving and suddenly it would not accelerate without trying to die. almost like it was running out of gas. very similar to the video below. it would idle, but would try to die when trying to accelerate.
I pulled the plugs and they were black so it seemed like too much gas (or not enough spark or air). I began by draining the gas tank, replacing the air and fuel filters and replaced the carburetor. next the coil. then the distributor cap and rotor. then the spark plugs. i clamped off the fuel line and let it run with the fuel in the bulb and it didn't change, so i eliminated any issue with the fuel pump. I finally called a mechanic that came out and basically went thru everything i had already done and left scratching his head. we played with carb settings, timing, checked and refreshed the points, checked the valve springs/valves, fuel flow etc...all the normal stuff. I have a condenser on order and if that doesn't work i'm going to change out the plug wires, although they appear to be relatively new. I love the jolly because everything is so cheap and it's fun to tinker with. that said, i bought this for my wife and she's losing patience

If anyone has any other ideas, i'm all ears.
