HAS ANYBODY TRIED SMALL 2 BANGER OUTBOARD MOTOR FOR A LIQUID COOLED PROJECT? I STARTED WUNDERING WHEN I SAW AN OLD CHRYSTLER 9.9 BLOCK ON A SCRAP PILE THE OTHER DAY. DON'T KNOW THE CC'S BUT IT WAS PHYSICALLY QUITE SMALL AND VERY LIGHT FOR 10HP (STOCK!!). HEY- SOME OF THE HOTTEST FULL SCALE PYLON RACERS ARE LIQUID COOLED. I'VE HEARD CONFLICTING STORIES ABOUT BALANCE ISSUES IF YOU TURN THE MOTOR TO HORIZONAL THOUGH..?????? SERIOUSLY HAS ANYBODY TRIED A 13MM CARB ON 30CC CLASS ENGINE OR JUST COMMON SENSE IT'S TOO BIG. I CAN GET NEW 9MM (LIKE STOCK WEEDTRIMMER) CARBS FOR $3 AND I CAN GET 13MM CHEAP BY THE BUSHEL BUT THE HOLY GRAIL 11MM IS ELUSIVE AND COSTLY.[IF SOME IS GOOD MORE IS BETTER AND TOO MUCH IS ENOUGH AND HOW DO YOU GET THE QUOTE INSIDE THE BOX?
