Low RPM @ WOT ??

[BlandingBoater]

I have a 1991 Larsen 18.5' open bow. It has a Mercruiser 4.3 liter with a Mercarb 2 bbl. Last year it would mostly run fine but had a little hesitation at WOT. It would occasionally kind of bog down when running down the lake at WOT for a second or 2 then smooth back out. Also when shut off the carb would flood out instantly and you had to wait 10 minutes or so to restart the engine. This last winter I cleaned and rebuilt the carb and replaced the float. The motor is running better without flooding but has another issue. At WOT the RPM's are low. If I back off the throttle just a little the RPM's increase to where they should be. Anyone have insight as to what is causing this issue and how to resolve it? I am assuming I need to adjust the throttle linkage. Anyone have a link to instructions with pictures of how to adjust it?

engine not running, put remote at WOT and look down carb, are the plates past full open and starting to close?

did you set timing/idle when you rebuilt carb?
