Well this is what I am trying for now. I bought a gallon of the seafoam, this **** isn't cheap it's $65 for a gallon, but I've used it to clean carbs in the past with very good success. Anyhow, I basically stick the fuel pickup line in the seafoam and run it until it stops, I'm letting that sit for an hour or so, then draining the carb. I'll let you guys who are also having issues know if it works, obviously I don't know how effective it will be.



As for me, in my boats and outboards I'm not using ethanol fuel anymore, **** it it's not worth it.

 

Damn, so THAT'S what's wrong with my weed wacker. It's got that yellow hard-as-rock build up, I rebuilt the carb, could never get it to run right, I'm guessing it's the ethanol issue.



I need to ask my dad what he uses, he has a 90 hp (or is it 110? I forget) Mercury "Saltwater" outboard with carbs and oil injection. He doesn't go out very often, but his motor always runs well. I know he fills up at regular pumps.

 

Yea the ethanol is a serious issue. I think I mentioned it back when you were talking about your weed wacker. If you want to clean it off take the carb apart and soak it in pb blaster for at least 2 days.

 

Like douse it, or get enough to submerge it?

 

You need to submerge it. I bought a gallons and I just keep recycling it, I pour it back into the can with a funnel.

 

Nice, I didn't know you could buy it in anything but a spray can.

 

The autozone near me sells it in gallons, I think it's $35 for the gallon, but like I say I've used very little and I have done this on 3 carbs so far with great success. I need to do one more which is my pressure washer.



Make sure you remove the main jet completely, if you can't get it out soak it for a day and it should drop right out.

 

I've noticed two problems, one is the float valve gets glued in by the ethanol guck and the second is the main jets holes get plugged. This **** is like glue when it tries you can barely chip it off. The first will cause fuel to simply pour out of the carb when you put fuel to it and the second will basically kill the engine when you give it throttle. It pissed me off the first time cause the motor was idling perfectly and as soon as I gave it gas it would die.

 

That's how it was for me, I could make it idle perfectly but not throttle, or it wouldn't idle at all but would throttle great.

 

If it won't idle it's the idle circuit, that's the jet on the outside of the carb, remove it and soak it with the carb.
