How to clean REALLY nasty jets?

[mattb348]

I was just wondering how to clean jets WITHOUT ruining them.

My jets are from a carb that literally sat outside for like 15 years (they were inside of a sealed carb though).

The jets were so dirty that I had to rub them with a brass bristle brush just to be able to read the jet numbers. There seem to be a nasty black film all over them in places.

I can see through the hole of the main jet, but the slow jet is totally logged (can't see through the main hole at all, or blow through it).

How can I clean the actual hole out? I don't think that carb cleaner is going to cut it in this case. I want to make sure that they have a clean hole with the right diameter (the crap inside may have made the diameter shrink).

Is there a good way for me to stick something in there to clean the hole out, without ruining the jets in the process?

try a lubricant of some sort like PB Blaster and use compressed air. it should do the trick

Jets are really cheap man. Just get new ones.

Try soaking the parts in Evapo-Rust.

I'd love to get new jets; the only problem is I can NOT find jets for a ytm200 carb for the friggin LIFE of me.

Every site that I have been referred to never has the right jets, and neither does ebay or amazon.com.

I even searched google...... and I am really good at google searches.

Still no luck...

I may have to buy a friggin used carb just to take the jets out of it, and hope that they are in usuable shape

Soak them in various chemicals then propane torch the pricks! That'll get any garbage out of the pee holes!!

I usaully soak with carb cleaner and then use a torch tip cleaner and run through them. the torch idea works really well and i totally forgot about it.

the urge will be to shove something through the holes,try not to.if you have to try something plastic or brass.

A torch tip cleaner works great for the main jets but the idol jet i use a tiny strand of wire and carb cleaner and just poke and clean .

I agree, go to your local welding supply and get a torch head cleaning reamer set. Soak the jets for a few hours or overnight in carb cleaner. The varnish build up should clean out pretty easy. If your local Yamaha dealer cant get the right jets somthing is wrong... They have access to OEM and aftermarket like Sudco. From the looks of it yours takes a small round Mikuni and a VM28 series Mikuni pilot. Here are a few of Sudco's jet pages you can order from them if you need to.

I use guitar strings occasionally but I usually just replace them.

Holy huge image above. I never have any luck cleaning the gunk out of really bad ones, and always replace them. I second trying your local Yamaha dealer. They may have to order but then you won't pay crazy shipping like most websites charge for little jets.

I would soak them over night in carb cleaner, then uses aerosol carb cleaner, I put the red tip inside the jet, using my fingers to seal it on the end, spray the cleaner through the jet. As long as a little comes out it will force the rest of the stuff out of there. Then plug the opposite end of the jet with your finger and force the cleaner through the side holes of the jet. This should clean them out good.

If you have to I usually strip a piece of copper wire (very thin stranded) and use these to clean the jets. Copper is softer than brass so as long as your careful it won't damage anything. But as soon as they can flow anything use the carb cleaner and don't try to ream them out.

I have never bought jets, call me cheap, but on a 4 carb bike its $80 for jets and I don't see anything wrong with cleaning them.

I burn the paper off a garbage bag tie and gently use the wire from that, if needed.

Permtax gasket remover works wonders...just let em soak
