2001 Johnson 150 Ocean Pro - Timing Adjustment?

[Mjreynolds928]

I have a J150VXSIF Motor with carbs. Can anyone send me a link to instructions or a video on checking and setting the timing on this motor?

The timing does NOT go out of adjustment on these motors.----If you are having issues do some trouble shooting.---What is your motor doing / not doing ?

Thanks. I changed the plugs and filters and put clean fuel with SeaFoam. I did the VRO bypass and mixed oil in with fuel. The boat ran better but somewhere between 2000-3000 rpm the motor shakes a little as if it’s struggling. Anywhere before and after that range it purrs like a kitten.
