can you tell me if you have ever or know of anyone who has taken the 4 cylinder 100 or 115 2+2 motors and installed 2 carbs on the bottom 2 cylinders with the carbs with the idle jets and how it has worked out.as far as motor performance any other adjustments that have to be done as i am very seriously considering this as my motor runs well in all phases except for pulling skiers and it is a bit slow out of the hole. thanx for your advice !
