Karla,
Would you believe the problem was the ignition module. I pumped fuel thru the carb and back to the tank. Looked ok here. I thought- well check the ignition with the spark tester I just purchased. Well, no sparks. (I baught a new ignition module and couldn't see any sparks, so I baught a second ignition module before I realized I needed a spark tester to see the sparks.) The second ignition module was defective and failed when it got hot. So I put the first new one back on and lots of sparks.
It now starts on the first pull. Bless the little spark tester or I would still be working on it. Ha Runs like a new one! You provided excellent, very detailed advice. Thank you.
Bill

Karla,
I dumped the old fuel and filled the tank with fresh Premixed two cycle fuel- no ethanol, 93 octane, with two cycle oil mixed (sold in quart containers). New spark plug, new ignition module, new carburetor, clean air filter. Its not getting that hot, but I will blow out the fins. The spark arrestor screen is clean. Combustion chamber looks pretty good, no excessive carbon. Seems to have good compression. This engine has a primer bulb for the fuel line to the carburetor. It hold fuel and does not drain right out. I noticed that after sitting a couple days, the fuel line to the top of the carburetor made noise- after I removed it from the carb. Like a small vacuum. I could put my finger over the open end of the fuel line and stop the light noise. I wonder if the fuel tank cap needs to be vented? I think I will try pumping fuel thru the carb with the primer bulb next. Thanks for your help. Bill
