Shot size is adjustable based on jetting... I have jets for 35-75HP here... New jets are easy enough to get though...
My jets are for EFI though, so you'd probably need bigger jets for the fuel if it's a low pressure carby setup...
It's a single fogger, so you'll need a place somewhere before the throttles, that feeds all the carbys to plumb it in... Does it run an airbox? Or multiple filters / trumpets?
