I recommend the washer shim mod to ANYBODY who is already breaking down the carbs. Factory they are jetted VERY lean, more fuel (to a point) is more power.
Kind of unrelated, but I had a modern 2.5hp 4 stroke outboard burn a hole in the cylinder wall because it was factory jetted to lean, just wasent ment to be rum like I ran it. Under More Investigation Simply Changing the jets would have given me at least another hp. That's the only difference between the merc. 2.5 and 3.5... lesson learned On Jan 15, 2015 5:53 AM, "Allen Thomas" <althomas...@gmail.com> wrote: > You have to remove the idle mixture screws if you want to get the idle > passages clean.
