Re: Merc v6 Carbs jet size /adjustment
ril0,
Check the number on your carbs again. I have no listing for any V6 with a WM carb, they are all WH.
The jetting for the WH12 is as follows:
All carbs the same (WH12-1, WH12-2, WH12-3)
Main jets - 0.048"
Idle jets - 0.060"
Vent jets - 0.098"
If you need an exploded view of the carb, let me know.
Cheers,
Chris..............
