One for the UBER GURUS!!!!

[bikerphil]

Kinda looks like SUGAR!????!!!!????!!!????

Now thats interesting!

[petejw]

Glad you found the problem.

That looks nasty, were the others like that?

If you've still got the old fuel filters blow into them from the outlet side into a white cloth and see what comes out of them?

[petejw]

just had another thought,
with all that muck on the outside, thats where air
enters, from the outside of the emulsion tube, fuel enters the emulsion tube from the inside, is it possible something has entered thru the air pilots in the back of the carb?

[blue giant]

In case you haven't thought of it, I would dump what fuel is left in the tank and see what comes out with it! Maybe even flush the tank a couple of times with fresh fuel!

[thewiz]

It might be ...

the Kreem???

[TopCatGr58]

Ever seen any crap like this?

Yeah, but Swmbo and I just wipe it away with a towel when we're done!

Kreem does look like the likely suspect sorry to say. T.C.

crud

I have been having the same symptoms as what Cobia is talking about. I will check these out and see if they are doing something similar. I had a crudded-up #3 carb float seat. Cleaned it out and she ran better, now I can't get it to start this morning....
Any ways, how are they removed?

[Cobia]

Haven't started it up yet, just replying....

Actually, I got the luxury of sleeping in and I jumped at it...... hadn't done it in a while.

Pete - Only 2 through 4 were like that, I was surprised when I got to #1 that showed no signs of it anywhere!!??
I did tap out the stuff out of the fuel filters, mainly what came out were rust flakes. This stuff is too fine and goes right through. Nothing getting in from back of carbs.

Blue - Did that for sure. Yet, unlike the cloudy sediment-laden fuel that came out of the carbs when I drained the bowls in situ, the fuel was clear and some rust flakes came out but no particles. WTF, Huh!!???

TC & Wiz - I suspect the Kreem as well, can't wipe it off though. Can't get my hand in there.........LOL!!!!!!

Chop - The main nozzle, or emulsifier tube, is held in by the main jet. In other words, you screw the main jet into it from the bowl side of the carb. But beware, it comes out to the other side. There's a washer under the main jet, remove it after you remove the main jet and you're looking at the emulsion tube. Notice it has a notch on one side, that corresponds to a pin or key that is built into the tower. Use an object of appropiate size to tap it down the tunnel and it will drop into the carb body.

I couldn't believe this crud, in one pic it had dried out in the other it's fresh out of the carb. Pics are a little soft, it's hard to do macro in the sunlight.









Ever seen any crap like this?

Ya that looks pretty ugly. When I rebuilt my carbs I cleaned those tubes on my extra fine wire wheel. They cleaned up real nice with no change to their dimensions. I run a fine spray paint gun cleaning wire through all the holes and never looked back. So . .did she fire up? Is the issue corrected?

[thewiz]

Talk about attention to detail ....

on my extra fine wire wheel. They cleaned

Soooo .... what do you think would be the right rouge if I was really gonna' buff my emulsion tubes 'til they shown like the sun, eh, Rob?

Swmbo and I just wipe it away with a towel

TC ... my goodness gracious ...

[Cobia]

Houston, we have lift off......success!!!!

She's purring like a kitten and running like a scalded cat now!!!!
That was the problem, but I would have been surprised if it wasn't considering the crud.
In the spirit of full disclosure, I just remembered that a while back I put in about 1/2 gallon of 100 to 1 two cycle premixed gas in it. But I've run about 5 gallons of fuel through it since then. Could it have "emulsified" that?
After all emulsification according to Merriam Webster is the process of:
": to disperse (as an oil) in an emulsion ; also : to convert (two or more immiscible liquids) into an emulsion"
I guess this may be the result of converting the immiscible liquids such as dissolved Kreem, 2 cycle oil, gasoline, and maybe some water, into the offending emulsified emulsion!!!! LOL!!!!!
Whatever, it's over with and I hope we're better for it, and learned something from it.

Thanks everybody....
Gracias Amigos.

If something else comes up I'll keep you posted.
I will reply to any and all questions in the spirit of CH 11.

Chop,

Something Cobis did not point out that may be obvious, is that you must remove the needle valve diaphram cap, spring, and the diaphram, slide and needle valve before removing the emulsion tube. It pushes out into the venturi section the slide is in.

[oldyam80sg]

I don't think it is Kreem.Almost looks like the Red Devil varnish remover i used before.Like i said i Kreemed my tank back in 1990 or before.Last year i thought i had a problem with my Pingel petcocks so i removed them from my tank to get rebuilt.Never saw any indication Kreem got separated from the tank and caused what you have.

[Cobia]

emulsion tube.....

Very true Don, those need to be removed. I was doing it all in a hurry so I forgot I did that. 2.5 hrs for a complete carb removal, disassembly, cleaning, and re-assembly, is pretty darn good in my book. Granted it's not like an initial cleaning of a neglected bike, but.....
BTW - This time I did one at a time in order to maintain some sort of order and sanity, and for the sake of expediency. It worked out pretty good. And also, I didn't have to set float levels either.
As far as the Kreem..... I couldn't tell you. One would need a orthoscope to perform an inspection. Besides, there are so many variables like if the process was done properly and the tank cleaned out correctly before proceeding with the three step process.
My local MC shop turned me on to this new sealant which is a sigle step process. You don't even have to remove the rust, it likes a porous surface to adhere to. You just have to make sure it's free of oily residues. I cleaned my 80G tank with a quart of denatured alcohol and that was it.
If anyone is interested I can take a pic of the can and ask the mechanic where he got it. I payed $75 for a quart and only used less than half to coat it. He later showed me a 1/2 pint can of a similar product guaranteed not to be affected by our new fuels. We both agreed it was the same stuff.

So... for now the crisis is over.

[DGXSER]

Cobia,
Yep, that is moving though them for sure. I knew you had the steps down, just forgot to mention, and Chop is acomplished enough that I figure he knew already to. Just one of those hate to say nothing and have someone less experienced read this and come back asking how to fix the needle or slide after they pounded the emulsion tube through it.

Given the amount of tanks that I have read on here to have been "kreemed" or the like, and the frequency of this problem, being never reported in the 6 or so months I have been around. I am strongly inclined to buy that it is the 2 cycle mix that caused your issue. Just glad you were able to figure it out relatively easily.

And TC, if it looks like that...see a doctor dude.
