John that is symptomatic of a carb that has an idle jet clogged. Happens to me every spring. Any gas, especially the crap we have now with all the corn in it, left anywhere in the carb turns to a solid and plugs small oraficaces. Best to have the carb pulled off and cleaned. One can do it themselves but it involves some nasty chemicals. The pros are set up to do carb cleaning and it brings in a lot of business in the spring especially. (I have a mower in the garage doing the same thing.) The idle jet circit is very small and easy to plug.
If you have the make and model of the engine, I can find some info on that it would take to clean or replace yourself. Otherwise pay a small engine guy to soak and clean the carb.
