Exessive smoke when accellerated after Idle.

[southshore]

Johnson 130 1995 Recently replaced plugs wires and coils

The engine is blowing gobs of oil out of the exaust(out of water). The engine is running a bit rough (idle). Mainly there is exessive smoke when accellerated after Idle.

I pulled 1 of the 4 carbs off it was in very good shape. They were cleaner than I would have ever though possible. The boat is curently in the water and smokes a lot and smokes even more when the engine goes from idle to a top end RPM. Seems like there is a mis at low RPM.

New Plugs and wires

Possible fuel pump vro or maybe a timing issue.?
How many turns on the idle air adjustment screw?
The Timming adjustment knob broke off last year it was replace but never re timed.

Re: Exessive smoke when accellerated after Idle.

check for air leaks in the fuel line.
if the fuel line sucks air it will overmix the oil and smoke alot.
also a fuel restiriction can make it overmix.
The VRO or OMS for your year is a very reliable device so i would check the fuel lines, connectors, fuel filter, primer bulb and all the joints of them first.

A good thing is: too much oil/gas is better than not enough.

What about a stuck thermostat? If the engine is running cold would it effect the oil/gas mixture.
