sure beast pulling them out

Here are the pics of my piston... it soaked in a potpourri pot overnight, with antifreeze, it did an ok job but not what i wanted.... it turns out i have the "new and improved" safer formula of antifreeze(orange color) that could be why.....so for peace of mind i so i went to the hardware store and purchased a gallon of mineral spirits and soaked my piston and cylinder head overnight....it seamed to get the rest of the carbon off.... i will fire up my motor tomorrow morning, and post rpm numbers after a few tanks, hopefully by this saturday if the weather is nice
