CARB DISSASEMBLY AND CLEANING *pic heavy*

[lee_dutcher]

well i got extremely board and decided to go out and take off the carbs on the judge. took me literally 40 sec (thanks to the pods). so this is what i discovered:

the jets under the carb bowl is 137.5
and the main is 180 across the board

the think acually looks pretty clean but for precautions i went ahead and and got some wire and poked through the all the holes pretty clean. only thing i got to do now is set the whole body in some cleaner to clean off the grease and grime. i also when ahead semi polished (not done just ran out of sand paper) he tops and im going to paint the bottoms (maybe the tops if i dont like it). ok fist thing i knoticed was that after i removed the slide the brass thing that the air needle slides into seem out of round some worse then others. would this effect the performance or do you thin it will be ok.

here are the pics

The pictures showing the "out of round" part is actually a little guard type thing that sticks up from the emulsion tubes. I can't remember exactly what I read the purpose of those guards was but based on personal experience my recommendation would be this...
1. Don't try to straighten them - they'll break off the tube and that will definitely change the performance from one carb to the next - don't ask how I know.
2. You're stuck with what you've got - the tubes are no longer available other then used ones- and they may not be better then what you've already got.
3. The damage was likely caused by a PO trying to pull the tubes out with pliers - don't make the same mistake, with the bowls off remove the main jet and tap the tubes out from the bottom.

I think what would be more important is if the actual hole down the center of the tube is out of round - allowing fuel to leak past the needle when it shouldn't but as I said above your kind of stuck with them.

The main is 137.5, and 180 would be the air jets.

Did you take the screw off next to the main jet to access the pilot jets ?
Stock would be 42.5 They should be taken out and cleaned also. Just be careful removing that screw it's easily stripped.

The needle jets you are concered about don't look too bad but I would replace them just for piece of mind. Lots of guys have spares kicking around.
Like Psycoreefer stated they can be removed easily from the bottom when the carb bowls are removed. I use a wooden dowel and a light tap they come out or remove the washer under the main jet and screw an old jet back in and tap lightly they pop right out.

They gotta come out anyways so the holes in the tube can be cleaned.

you talking about the big metal flat head screw? no but i will thanks first time cleaning carbs...lol... think it will be ok to put the carb bodys in a hot tank for a while? i think i might get plasic floats to. as you can see that the brass one are kinda gross but i might let them sit in clr

[CatatonicBug]

It depends on what is in the "Hot Tank". Don't soak the carb bodies in anything corrosive (like carb cleaner), or you will damage the butterfly shaft seals. I have heard of some folks soaking in Simple Green or even PineSol with decent results, but be sure to rinse them off thoroughly, as the Simple Green can eat the aluminum if left on it too long.

Unless your floats are not floating, I's say to leave them. Plastic floats are fine, but why spend more money when you don't have to?

well i got a sh*t ton of simple green ill soak them in that. but rinsing them in water? wont that corrode them more?

[CatatonicBug]

Do you get all the water off your bike after it rains? Or even after washing it? I doubt it... A thorough rinse in warm water will get the Simple Green off, and if it's warm enough, the water will evaporate quickly. You can use a carb cleaner spray and compressed air afterward to be sure.

Those floats do look to need a good cleaning. The plastic floats are nicer and less problematic as to getting holes or denting and such. But they are not cheap.

Like everyone has stated, I'd definitely pull the emulsion tubes out, and also the pilot jets (under the flat head screw) I also pull the mixture screw out and clean those thoroughly. Cleanliness is not just next to Godliness for carbs, it is mandatory.

As to the tops of the emulsion tubes, look at your needle jets, and see if they are rubbing against those bent in edges. Honestly, those bent edges will effect air flow and therefore on some level the carb performance. But if you have not noticed it, then it probably is not significant. If it were me, I'd see what new (gently used) emulsion tubes cost, and see if its worth it to you.

....err...you mean, 'push'...right?

yamaha sales one of the best carb cleaners they are for about 9.00 and all the mechanics here in NC say it is the bomb.....story behind that but i wont go there now....another on bike thingy they do here in NC is use a gas additive they sale at the parts house ....cant for the life of me think of the name now i just worked 12 hrs. on nite shift....

....err...you mean, 'push'...right?

Call it midwestern slang for remove them. But yes, I also use a wooden dowel (since wood is softer than the brass and will deform before the brass emulsion tube) to drive them out from the bottom or main jet side.

Note, only try this AFTER removing the cap, spring and diaphram with the needle jet in it from the top side.

Lee, i have emulsion tubes and plastic floats if you need any

pm me some pics of the emulation tubes and throw me a deal then maybe. i have all winter to clean these carbs.

Carb Cleaning

Lee Be very careful with simple green. Only leave them soaking for about 30 minutes and never let it dry on the surface. Rinse with water right away. I had a bad experience with this stuff last year doing my carb bodies. I managed to scrounge a few extra sets this year and found myself a large ultra sound machine with a heater in it. I got fantastic results using hot water and dove dish detergent in the machine. And using a tooth brush on the real bad spots. They all look like new. No need for harsh chemicals at all if you can find someone with an ultra sound machine.
