It really sounds like it's trying to start.
You can try a shot of starter fluid. Exactly when the engine fires, mash accelerator to 50% or so and hold it for 10 seconds. Always worked when I had my frequent k jet problems. In fact, I made it a habit to start with the accel pushed only partially so it would start up 99% of the time. If you mash it to the floor, it may not start at all.
As for gurgling... Oil? Maybe coolant?
