Is it beyond the warranty period? the normal cause is a carburetor diaphragm that needs replacement. Provided that the primer works, the rest of the carb is likely fine. The diaphragm is located in between the fuel tank and carb and is an easy fix. Remove the airfilter assy, the two tank bolts, and the small spring watching where it attaches. Then lift the carb/ tank assy off in such away that you can twist and unhook the link from the carbs throttle shaft-watching how it attaches. The carb is attached w/ 5 screws. The rest is cleaning it up and installing the new kit, diaphragm below the gasket (on the tank side) and reassembling. Tighten the 5 screws evenly and in a staggered pattern and you will be fine. Reassemble. How does that sound? Doable?

Thanks for your answer. Yes, unfortunately, out of warranty. I'll do as you suggest as soon as $$ permit and post the results.
