Hopefully this question makes sense. I have a 200 hp johnson 1996- j200stledm. The engine at idle runs fine no spitting or bogging and it also starts good to. Once i put it in gear it still runs fine, but when I give it a little gas (800rpms slowest) to about 900 to 1100rpm the engine shakes quite a bit. It has never done this before until recently. <br />Quick background, was going to take apart and clean carbs due to im down a few hundred rpms from normal (5500rpms being where i was before and now only getting 5100rpms with same set-up) Had buddy- (a mechanic) talk me out of it since he checked and said they were fine. I still was not sure so i took it to a mechanic and he said no need to do the carbs and replaced the power pack. The engine still shakes and i'm stuck<br />Do you pros think my carbs are causing the shaking or something else like worn splines<br />Thanks for your time and knowledge
