no, i'd say that you just need to let it idle and warm up a bit longer, it's prob the colder weather.

and remember with the choke on you don't need to give it any gas on start up if you do you'll prob flood it, just give it 30-40 seconds to warm up

and the minnarelli prob has a stuck piston, you could just spray some oil in the spark plug hole and let it sit for a few days -might free up. other than that you'll have to pull it apart and see what's the problemo.
