TT .40, idling rough, spitting unburnt fuel through the exhaust.

I let it idle for a minute or two, but when I tried to accelerate it didn't want to do that.
Then I noticed the puddle and shut it down.

I'm thinking it's rich. But I'm asking before I start fiddling with things that could make it worserest.


(Worserest means I might make it not run at all.)
