Thread: I've got some pretty bad wash

I've got some pretty bad wash, update 5-27
This is after about an hour of use. I have the center running super rich (I think a 152) because the guy at the shop handed me the wrong one and I decided to run it just to check it out. I'm concerned about the mag. I think the PTO looks ok.
Also, this is not directly after a wot run, I had to come back into the launch relatively slowly.

That center one is fat[rich]
The PTO looks good, the MAG is a tad lean. its not too bad.....I would fatten[richen] up the MAG some.

What is smeared on the jet block covers?
Make sure the vent hole at the bottom of those covers is not blocked ( it would increase the pop off pressure,possibly shut off fuel in certain conditions )

the mag is a 140 stock,i'd go 142,maybe 145 for the cen,but a 142 might be fine there.you dumped the injection and went premix??i might have a couple 142's

Took it out today again. I have about 2 hours on this rebuild now. I must say that something doesnt seem 100% right. It seems to be lacking some power and is overall a bit sluggish feeling. Here is a pic of the wash. This is taken during a 30-45 second wot run, and the stop switch was hit while still at wot, and I then got towed in. (This sluggish feeling may be due to the old gas, old plugs, and the overmix of oil)
My concern is mainly with the center cylinder. I am running a pretty big jet, so I was expecting it to be rich, however that's exactly how it looked when I checked last summer before the crank seized. Anyway, here are the pics. (Sorry for the bad pics)

check the screen for the center carb again,make sure the carb base gasket didn't move as well.

I just pulled the carb. I'm currently running MAG 142 CEN 152 and PTO 142. When I took the carb off, I did notice that the center lower carb gasket was not seated correctly. What should I change the jetting to? I'm thinking 145 148, 142.
