I disassembly the carburetors of my Yamaha 200 1994 for cleaning and inspection.
The carburetors type is 6R401.
I see that the middle port main jet is 158 and all others are 154 (the cylinders on port bank are 2,4,6 low cylinders). I see another 200 hp engine with 158 main jet is on starboard middle!
What is the corret main jet configuration?
Why the main jet aren't the same for all cylinders?
What are the correct value of pilot screw turns out? Are the same for all cylinders?
Please can indicate me the correct value in compression test? It's the same for all cylinders?
thank you very mutch for the help.
