88 Accord died while driving

88 accord DX +250k, carb, very likely withth original engine, manual tran.

early morning, I was going 50mph and the engine just died ( I think the check engine light came on first). I was still in gear and notice that the rpm was going down smoothly with the decreasing speed and I step on the gas but there was absolutely no respond, no hesistation from the engine. I just went smooth sailing dead.
Now it haven't start once or try to kick it, and no hesistation either. I've check for sparks (thats a go), disconnect the fuel line (just added a full tank) and observe fuel spurting out when I crank the engine. Spayed some starting fluid to check for health of carb. (An auto part attendance gave me the idea, I didn't sprayed too much though) but nothing change the engine just won't sput even a little bit, the starter turns the engine fine, i've even put it in gear while cranking. Some how the engine won't catch? It had been doing fvery fine before, just one turn would start like a champ.
