I think I make a boo boo

I was dissatisfied with my Craftsman 675 series tendency to bog down and I rigged the throttle to operate faster. Within minutes the darn thing shut down and when I went to start it back up, I blew smoke out the engine. Not the muffler, mind you. I just packed it up and called it a day but considering the symptoms, what sort of damage can I expect to find after over-accelerating?

Where did the smoke come from? What color?

When you pull the recoil starter cord, does it feel the same or easier ?

Over speeding the engine is never good. Possible valve train/connecting rod issues.

The smoke was thick white. Sort of like cigarette smoke. Not like puffy smoke from the muffler. The pull feels the same and there are no unusual noises. I opened the valve cover/piston chamber and there is caked on burnt waste but I cleaned most of it up. Still no start.

Again where did the smoke come from?

Do you have spark?
