How to clean idle jet

Postby lowmanj » Sun Jan 30, 2011 11:27 pm



I'm rebuilding the dirtiest '81 carbs in the world (see pics).
While it's cleaning up pretty well, I am afraid the idle jet may not be clean enough.
I know it has to stay in, and be "cleaned" in place. How best to do it, and how can I know it's cleared before I reassemble the carb?
Thanks very much.
Jesse

Well..I'd pull them..as they have side ports which can't be cleaned in place. You can find a wire..I am told a guitar string the smallest fits in but that only reams out the main port. To remove find a sheet metal screw that fits in..turn it in lightly until it grabs and then gently pull.wiggle, rock, etc until it breaks loose. It can be pulled. Just be careful
not to chew up the end too much. An easy out can be used to just need a small one. Letting it sit in some solvent like Blaster or sea foam first helps to.

I have read of people boiling their carbs, I have never done it, I went thru a few cans of carb cleaner on mine though , a air compressor helps, if you don't own one just get a can of compressed air.. :D

Some prefer brake cleaner.Don't forget the air cutoff valves(4 of them).

Yes for sure, and don't go and lose one of those tiny o-rings, they like jumping away sometimes..The fool that worked on mine had one missing...Golly gee..Mine was a mess man..

I have been hitting the idle jet (in place) with PB Blaster, brake cleaner, carb cleaner spray, carb dip, bathroom cleaner, and water, and compressed air, alternately. I also reamed it with wire. A single strand from standard wire brush works very nicely.
But I have a Missouri attitude; show me.

"To remove find a sheet metal screw that fits in..turn it in lightly until it grabs and then gently pull.wiggle, rock, etc until it breaks loose. It can be pulled. Just be careful
not to chew up the end too much."


If I did pull the idle jet, does it screw out, or pull out? Will it come out as a single piece, or more than 1 piece? Will I see washer? How many o-rings? To re-insert is a "press-in"?
Also, the Randakk master kit has some extra o-rings. Would any of the extras fit the idle jet, by chance?

Thanks very much
Jesse

You know what the main jet looks like, it looks like that, and it's only the jet with no threads or anything like that...It's about a inch long..Using the easyout tool bit breaks the seal and you really don't have to pull on it at all..But do want you feel is best..

Am I wrong?Isn't the 1100 idle jet threaded in?Look at the end of the jet.If it's slotted,it's threaded.If not,it's punched in.At the throttle plate are 4 holes,just behind the idle mixture port.When you spray up the idle jet it should come out all 4 holes(and some out of the idle mix port).Prop open the throttle to see.Watch your eyes.These ports are for Off idle running.A plugged hole can cause noisy(clattering)acceleration.An uneven fuel flow between cyl's.

Just did the ones on the project bike. Here's how bad they looked, soaked them in 1 part Pinesol to three parts water for three days. Then spryaed them with barake cleaner. Boiled them in Lemon jucie and water for about an hour each. The bristle out of a wire brush cleaned out the remaining junk. One last shot of brake cleaner then compressed air, look like new.

Great information! Thanks all. Yes, these "81 idle jets are pressed in. I decided to not remove them, following the Halasz book to the letter. I am confident they're clean though. I'm getting the spray coming through as mentioned in one of your posts. The photo I posted turns out to be one of the cleaner carbs!
I'm disassembling one at a time for clarity. I've never had this many parts laying on the bench at once.
Pretty psyched so far. Two down, two to go. I'll replace the timing belt before I run it, but I'm excited to hear that smooth hum again after all these years.
Looking at these things carbs before cleaning, I'm amazed I got it to even run for a few minutes. No wonder it sounded scary-bad.
Thanks all for your help.
Jesse

I had the same problem with my carbs. Took them to a shop who had them for three months, keep spraying them with cleaner and could only get a couple clean. I once seen an article about boiling the carbs in lemon water so I gave it a shot. Used one of my wifes big pots, which she was thrilled about.... and filled it three quarters with water and dumped a whole bottle of lemon juice in. Boiled one end for ten minutes then the other end. Took the carbs outside and blew air and carb cleaner throught all the areas I could and put them back on the bike. Thing runs like brand new!!!!

found removing idle jet easier than predicted-was ready to sell bike on craigslist after carb rebuild-boiled carbs before rebuild-randakk kit-still ran like crap-someone suggested idle jets-being stubborn, i refuse to believe, going thru everthing else possible- getting tired of removing carbs-decided, what the heck i had second set on carbs to practice on, i decided to pull jets out of them-sprayed them with pb blaster -used screw(what i call sheet rock screw-very sharp-1 inch) turned into jet until it stopped-used wire cutter pliers, grabbed screw with cutter part and pried up, jet came out-it would be impossible to clean in carb-it has several small holes on sides and i had to work a strand of wire brush through bottom hole to get it clean- used drill bit (by hand) to dress up where screw went into jet and down shaft(so as not to remove material, just clean) tapped jet back into hole with stub end of drill bit- bike runs like new-money couldnt buy it from me now. hope this helps someone else, thanks

I soaked mine in Seafoam and 24 hours later, all the grime came off easily with an applicator stick (q tip but with stronger cotton and a wodden stick).

You can also remove the aluminum plug close to the idle bleed screws. Just drill a small hole in the center about 1/4 deep, screw in a sheet metal screw or whatever, pull and they come right out with decent pliers and a screwdriver or some kind of prybar. You can then see the idle holes into the throttle body throat. Easy to clean the idle circuits this way. Use lots of crab cleaner and compressed air. Smoke test with a vac hose and whatever smoke you choose....recommend legal stuff though :)

Oh, be sure not to drill hole any deeper than you have to, and tap the plug back in....


Hope this helps someone.

I took my carbs apart three times before I finally solved the clogged idle-jet problem. Here is a photo of me extracting the idle jet (ignore the cracked tower, a previous owner did that). Here is another photo of me cleaning the jet with a .013 guitar string. Idles much better now.
