Re: What causes this grey emulsion?

[Don]

I don’t understand the poor running symptoms you mentioned, you seemed to say that you had to run it with the choke out somewhat, but it was too rich….
In any event, you will get that kind of emulsion slop drooling out when the engine is not running correctly. Put it on a boat and give it a good run like everyone has said, dial in the high speed needle before adjusting the low speed needle.
