Default B&S 5hp Help

Have a '77, 5 hp, B&S with a pulsa jet carburetor. Replaced points w/magnetron coil & ran it 3 times & on last run it had a loud squeal followed by puff smoke then off. Believe the starter clutch miscued which caused the squeal as well as sheared shaft key. Replaced key, cleaned starter clutch, have cleaned carb many times, spark plug appears damp from fuel, pulled head & there was minor carbon on valves. No compression when testing, but not sure if this is typ w/a pulsa jet carb. Pressure does come through carb

Cannot get the engine to start again & not sure what to ck next. Suggestions appreciated
