Broken fuel jet problem

Anyone have any ideas on how to get a broken fuel jet tip out of the carb??? I've tried soaking in carb dip...spraying with carb cleaner....boiling the carb...using a fine wire from top and bottom.....
Any suggestions would be appreciated...I've run out of ideas.
 
The last set of carbs I did ('79 550) I had to remove two broken tips. I just laid a flat-blade screwdriver across the tip and pushed it down.

I don't know if it's normal or not, but you could feel both of these tips sticking up into the carb throat, so I just pushed them down with a screwdriver blade.

.
 
you have the most complicated and delicate problem I fear on every set of carbs I disassemble.

a machinist scribe 90 deg. pointer tip. poking into the body downward through the venturi. compressed air with a 90 deg home made hose tool. use fluid to help seal when using the air. propane heat on the carb body will loosen the 2 materials apart from each other... then blast it with 125 psi directly in the output hole.


do not mutilate the output hole much

just remember some people should never touch the carbs by themselves. it may save a guy a bunch of time trouble and money just to let /pay a experienced mechanic to do it right.


it really takes a load of force to do that to a carb mix screw.
 
So I finally got the tip out but I'm afraid the output hole is larger now..arrrr....I am guessing the carb is toast now.

It will work itf it's not too boogered up...Might just need to turn the screw to a different position than the rest.
 
Well that's all the encouragement I need. I know everyone on here is saying 1 turn out for factory set, so I'll maybe just make that one 1/2 or 3/4 turn out. Thanks for the support. I can't believe how wedged that tip was. No wonder the bike was stalling at idle.
 
You must be mad......

No you pay the experienced mechanic to snap the tips off in the carbs in the first place. Then you fix the thing.

I do not know any mechanic working for a dealer today that can work on any of our classic GS's. If you find one that won't ruin your bike treat him with great care and box him up with cotton wool and fine anti rusting agent. There a rare breed.

I put my 2002 bandit into a large know UK dealer and they messed up my carbs which I fixed. All 4 mixture screws through the carb body, I could touch the tips. If thats the state of a mechanic today.........

Suzuki mad

The bikes all back together. She's running pretty good but either I have a bit of a vacuum leak as she runs just slightly rough at idle at times and although the #2 carb, that now has a much bigger hole, has it's fuel screw WAYYYY down, the bike stalls when taking off from an idle, unless I feather it. As soon as I put the gas on I loose vacuum just for a sec, enough for her to stall. Not sure if thats from the #2 carb or a lean mixture. The valves are done, air box done, carbs done and synched. She is running much better than when I got her though. Had a nice ride today finally.
