Problems with 1987 VRO johnson 90 hp falling down when i throttle up

[stevedavis183]

I recently bought this motor and fixed the first problem,but now when i took it out to try it. Just as soon as i got in to it it started bogging down and running and sounding like crap any help would be greatly appreciated. Thanks Steve. ALso does anyone know what side of the engine #1 in on and is it top or bottom.

I'd rebuild the carbs to start, that the most common problem to cause this.

I checked the jets and ran a line wire threw them they r clean. Do u think that the stator or the spark advance could be the problem?

How many jets? I can't remember how many mine had but there are a few, the main one is behind a screw in the bottom of the carb. I'd recommend taking them apart and make sure they are very clean.
