Ok. The mod thats you need to take out the airbox snorkle and the spark arrestor and buy the carb parts for the 150, now, The baffle in the middle of the spark arrestor (i guess it is called quiet core.) could I take it out only instead of the whole baffle, and still get power? I have a Powroll end cap, but i wanna do the mod instead. Thanks.
