I realized for the first time today, or found today. the petrol drains in the front and rear of the bottom of the inlet manifold of my 3000 BN7. I see them in the catalog, but not in manual.
I tried to look at the previous threads to find an answer for my question ...... These let air in, like a vacuum leak, wouldn't that make run lean, so when you adj carb mixture you are adding extra fuel to compensate for it??. I see one of mine is plugged and the rear one is not.
So thats my question, does't it make it run lean??? So you compensate for it when adjusting carbs at idle??? Isn't that like having a lot of throttle shaft clearance??? That causes a problem, why would this not??
