I finally got my 66 roadster on the road after quite a bit of work.

I'm having a problem I haven't been able to figure out.

It runs fine at idle and driving around at low rpms, but when I drive at high
rpms, it quickly starts to sputter, and then immediately afterwards sputters
at the low rpms. It recovers after about 30 seconds and then runs fine again
at low rpms.

I thought it was a fuel problem at 1st. I checked fuel pump, floats and carb
adjustment with no change. Then thinking electrical. Changed spark plug wires,
double checked points and timing and no change. I don't know of any elect.
issue that would cause it to sputter at high rpms and then still run bad at
low rpms and then recover after 30 seconds, but I don't know everything.

I did just think that there could be some fuel blockage between one of the
float bowls and the carb.--I'm going to check that now.
