Thank you. Hose is new, so is fuel pump. Took off air horn immediately after safely getting off the road and fuel bowl was filled to specification, float and needle valve were not stuck. (I've learned to carry tools and spare parts; ie coil, points, condensor, gaskets, blah, blah.) I've had coils in the past fail when they got warm, but a cool brand new one made no difference under warm block condition. It's got the old Ford dual carberettor rebuilt, and I didn't see any cracks or other damage. This one has me stumped.
