New to the forum and snowmobiles. Looking to see what carbs are on my 570E. I believe they are mikuni VM36 or 38. I've looked at mikuni sites and narrowed it to those but I need to know a few specifics about them. Like what are the 2 ports on the side that appear to go to the water pump? I can't find them in the factory service manual. Also,how do you set-up the electronic switch that's hanging on the side? And how to test them to make sure they work? Again,nothing in the manual.
