1986 Johnson V6 225 VRO driving me crazy.

I've been trying to get this motor running right for ever. Runs fine on a hose but horrible in the water. Won't idle, or accelerate but runs at top end great. If you give it full throttle from trolling it will sit there at low rpm for a min and then for no reason get to speed. Also, plugs for all cylinders are covered with oil like it's getting way too much but it's a brand new OEM VRO pump.

Has good compression, spark, carbs are all cleaned and inspected. New VRO pump, one new power pack. New plug wires.

When the air box is off one carb bank seems normal but the other one spits gas out the carbs and puffs and spits sometimes. It's the side with the old power pack. I was thinking reed valves too but didn't want to completely take all carbs off to check. But would that make all the plugs foul?

When I took the carbs off the bowls were all full of fuel.

I am going to replace the other power pack once it gets here. But other than that I am at a loss.
 
Took the carbs and reed valve plates off. Reed valves on that side were toast huge holes in a few of them. We'll see what happens after I replace them
 
I found some used OEM assemblies on eBay I'm going to put on, otherwise it was going to be $1200 to buy six all new assemblies. It's crazy 2 strokes are supposed to be the simplest kind of engines and this is the sht we have to deal with.
 
Agreed----Carbon reeds have a finite life.----And agreed some things are expensive.----Check prices of parts on 4 strokes BEFORE investing in one !
 
Got the new reeds installed and the thing is running pretty good, especially out of idle. I'm still getting some coughing backwards out of what I think it's just the #1 carb at idle. I'm thinking it's running lean. I was thinking of changing all the idle orifice screws from #20s to #18s or #16s because it's still not idling great all the time.
