1997 merc 40 4 cyl 2 stroke with a Brand new CSI stator
Starts and runs and I adjusted it per the manual for carbs and timing
BUT
It does not run smooth at low speed and at idle or anything below 2500 rpm, above 2500 it runs like a scalded ape, smooth and vibration free matter of fact the boat is 5 mph faster with the new stator
The carbs were just cleaned and had a kit installed and the gas is new and it has new plugs
I need simple to understand timing and carb adjustments, this thing is supposed to be real smooth at idle and at low speed because it is a 4 cylinder
Can I time it at idle? the book says do it with the motor off using the starter motor what should the timing be at idle?
Can I adjust the carb at a speed other then idle?
