1988 Force 125 forward won't rev more than 2000 rpm

[fitale]

I just got this older boat 1988 Bayliner Cobra 1800 with Force 125HP outboard 2-cycle motor.
Yesteday first time took it to the river.
In forward gear it revs only up to 2000 RPM but in reverse it goes to 4200 RPM. Where do I start looking?

thanks

Click on the link and synch FAQ on the sticky posts (top potion of the forum). There is a section in there on how to synchronize the carb and timing linkages. Doing this will tell you if the throttles are actually going in horizontal position at WOT.
