Voila!! I did what Mike (Sorekiwi) suggested first: check the spark; it had spark, so I thought - spark, OK, then it needs GAS. So, I took the gas line off the carb side of the fuel pump and gas poured out and apparently had been airlocked. I re-attached the fuel line to the carb. I climbed aboard, and the engine took right off and runs awesome smooth and strong - BOO-YAH!! I have my C160 back, now to start on the tiller and then the C-160 hydro (needs head gasket for starters), and then my B-80, and then the 520-H.
Thanks to all for the great tips and advice - it worked and I'm a happy guy.
