Lol thanks... I pulled the carbs off yesterday because i'm making the primer pieces to press into the holes where the choke rod/flappers used to be. And once i saw that line i've been trying to figure out what it is. It wasn't hooked up to anything but the ski wasn't complete so i'm doing my best to get it back together properly. Any help would be appreciated.
thanks

pretty sure thats where the stock oil injection feeds in on those carbs. for sure if the intake manifold doesnt have nipples on it.

Like buzz said it's the oil feed

 

[Matt Mullin]

So do i just block them off? Im premixing the fuel for it so there is no need for oil injection.

if running premix then just cap the nipples right off carb
