I have a 40 hp motor and last time out it idled and road rough up to 2,00 rpms so I took the carb off and cleaned it. as I took it off I noticed that the cam follower roller was loose. So when I put the carb back on I reset the idle screw, can roller and oil mix screw. Runs fine at idle in neutral and in neutral up to 4,000 rpms. So I took the boat out today and runs great in neutral but when you put it in gear and runs good upto about 2,000 rpms then bogs down and sputter and spit til it shuts off. Kinda confused what it could be when all I turned or adjusted was the idle screw and oil mixture screw. Any help would be appreciated
 
Carb cleaning didn't get out all the gunk. Fill the carb w/SeaFoam and let it sit for 2 days then run her hard. She'll smoke a lot for awhile.
