Green powder mold? on carbs?

Hello Dear XJ Friends,

It has been a while since I have visited. Life has gotten in the way, in a big way...

Anyway, haven't been taking Rosie out much, after the carb rebuild. She was tight! Ran better than new! Even with my big butt on her...

But, as of late, fuel continued to flood the bike, oil bath, and my garage floor.

I finally go around to cleaning the carbs, and low and behold, there is a TON of this powdery green mold, that is everywhere! There was so much in the fuel rail, that each float screen had a festive Christmas green hat!

The bowls are so full of this crap, that you can't see the bottom.

And all the brass jets, fuel pipes, (new ones), are all corroded and nasty. Even the new seals I installed, on the fuel pipes are jacked.

So, what caused this?

And, more importantly, will I be able to clean all this stuff off, or will I have to buy all new again?

Thanks for looking.

 

Sounds like seafoam residue. Yup spray cleaner will get it.

 

seafoam doesn't leave a residue.

Sounds like some bad fuel and some water got in there.

 

I have never used Seafoam in this bike.

I had been using "Enzyme" to combat ethanol, but never had this happen before.

I could definitely believe the bad gas suggestion! The gas sold here, in Aggieland, is so crappy!!

Has anybody ever tried soaking the brass bits in "Brasso?"

If the O-rings, for the fuel pipes don't hold... Chacal will be getting another order!! LOL

 

I usually try to use Chevron Premium, around here...

Seems to be the least nasty.

 

Here are some pics, of the bowls. I should have taken a pic of the fuel passages...

 

Your fuel appears to have been infected. Though less common than with diesel, gasoline can become host to bacteria and fungi. Do a thorough soap and water cleaning, followed by carb cleaner to get the water out. Before anyone jumps on the ethanol blame wagon, this sort of thing happens to all grades and types of fuel, particularly during long-term storage.

 

AggieLand, eh? I spent the better part of the 90's up there getting an education. Haven't been back since they stopped building Bonfire.
Start with spray cleaner, if it works, it an easy solution, if it doesn't well you're not out much.

 

I already tried my carb cleaner, and it does not remove the green stuff.

I am soaking the brass in B-12 chemtool, right now.

Yeah, Hank, I was at the last bonfire, good times...

And the carb bodies are "stained" with this green muck. So, I gotta try to find a solution to remove it from the carb body.

 

One thing is for sure.... It is not from Seafoam. I use Seafom all the time to clean out my carbs. I will use Seafoam every 3rd or 4th fill just by adding 3 oz. to a full tank. I found this helpfull and this may be something you want to do in the future.

 

Here in snowmobile land, we call it 'green disease'. LOL

The reason we are saying it isn't because of seafoam is because someone else posted "sounds like seafoam residue", not because we mis-understood you. No worries.

Unless, of course, some foam from the sea actually got in there..........but then the salt would cause other issues-------- LOL

Soap, warm water, and an unwanted toothbrush.

 

The seafoam thing was mine. I had to clean my brothers where he would add almost half a can to a tank of gas then run in into his system then let it sit till it dried. That happened several times. Listen to the experts, not me.

 

I had a thought, I used silicone grease, to put the new O-rings in. Could that have reacted with the gas, and cause this?

Brasso made quick work of cleaning up the brass bits.

That is a piece of scotch tape with one of the festive mold hats. It fell apart in the tape.

This may end very will for Rosie!

 

is there any bread in your tank?

 

Bread? Oh, that is where I left it! Duh! LOL!

 

Hey skippy,
Have you tried soaking your carbs in one of those buckets of carb dip? It worked great for me, I soaked all the aluminum parts overnight and just sprayed em out with canned cleaner. I didn't have to scrape anything and they were spotless. You have to disassemble if you want to soak the carb bodies, but if you haven't replaced all the seals in there then you will probably have to do that anyway to get it tuned up right when you put it all back together.

 

I have not done the carb dip, yet. I have been spraying and scrubbing.

The gallon can of B-12 Chem tool is $27.

And yes, I tore them apart last year, and got all new "stuff" from XJ4Ever. Thanks, Chacal!! Seals, O-rings, float needles, etc, so I am good there.

And yes, I remove everything!!

May have to indulge in the gallon can of B-12 Chem tool.

Do you all just dip your carb body in the gallon can, and reuse for all four bodies? How many "dippings" can I do, before the chem dip is all used up?

 

FYI, I'm pretty sure the Berryman (B-12 Chemtool) products do not eat rubber and plastic (hence the plastic dip tray)....although I personally would still completely disassemble my carb...and I would never subject the rubber seals to a carb dip.
Was recently at a trade show and spoke with a Berryman's rep...he was the one who clued me in...

 

OK, so I went out and bought a damn gallon can of Berryman's B-12 Chem Dip... $27.99 @ Oreilly's.

Got a carb body and a float bowl soaking right now.

We shall see what happens!
