Problem's carburetor icing. Very common when temp's between about 30 and 55 and with high humidity. Things that help:

- Use minimum choke when starting. Once the engine's running get the choke full open as quickly as possible.

- Immediately after starting idle the engine at 1/2 throttle for several minutes. Or run it at speed under light/medium load. (DON'T let it idle at slow idle until it's fully warmed up!)

- If the still engine dies after running a couple minutes, wait 5 minutes or so before restarting so heat can soak down from the manifold and warm the carb. Or play a hair dryer on the carb for a couple minutes to warm it up.

- If icing is frequent and extreme, cobb up a hose to draw warm air from around the muffler into the air cleaner inlet.
