Greetings. Having trouble tuning sled. It seems we get a lean condition on idling. Like there is a vacuum leak. It will idle but all of a sudden she will rev up.. We removed and cleaned carbs. We checked carb boots and main seals.
Before all this started we discovered the oil reservoir was cracked and leaking oil. So we changed it. And now we are not sure of the vacuum line #16 in the diagram.. Where does it go? Also the port on the manifold directly under where item 16 that appears to be open to atmosphere. Is that supposed to be plugged? Anyone have guidance of where this hose goes and that port under it? Any pictures?
Appreciate any help you can offer.
Item 16 hose and suspect port is top left in picture if you can't make it out.
