Half the main power jet twisted off when trying to remove, how do we get the other half out of the bottom of the carb?

1 Why on earth were you trying to remove it??!! Just can't resist jacking with things? Well, now that you have made that mistake, the best thing is to select the proper left hand drill bit size and try to unscrew your screw up. Beyond that you may, if that fails, drill out most of it & then carefully pick out the remaining bits in the threads of the carb casting. If you drilled too much off center, then you can throw it in the trash. Recovery from your mistake depends on your skills from here forward. In the future, leave well enough alone. Remember, a carb is not a mountain to climb, just because it is there. Please respect my "insensitivity" as much as those who want me to respect their sensitivity.

Have you messed up the hole in the jet? Usually you just break off one side and the hole is OK. If that is the case. Clean it up the best you can - run a soft wire through all the passages and blow them out with compressed air. Then give it try. Might work, might not.

The other option is to give GB in MT a shot at it. His work on old M/S carbs is phenomenal. I'm sure Gary will be along shortly.

Lisa,
How long was this piece of main power jet that twisted off? I am feeling you may be talking about the main nozzle. Let us know what the twisted piece of brass looked like. I may have a solution.

At this stage I would send it to Gary in MO or buy a new one. Removing the remainder of that jet is above my pay grade.

Lisa;
Until we know what you are calling the "Main Power Jet", stop working on it.....!!!!, OR as JMOR has already told you, you may just be buying another carb.
Is it the Main fuel adjusting needle???? That is the adj. screw, on the top of the carb front!! If that is what twisted off.....then you will have to have a special pair of 90deg. vice grips to get it out. (DO NOT DRILL ON THAT ONE!!!)

If it is the main NOZZEL....the the right size drill and some dental tools are needed, to remove what is left in the passage.

The easy one of the three to remove.....is the Main jet itself.......(Right sized lft. handed drill......Centered.....then re-tap new threds for a new jet!!!!

Tell us exactly what you broke,.....then I might be able to help you!!!!!!

The power jet under the main nozzle. The carb was off the tracor that had been sitting for 15 years. The carb was rusty as heck inside and between soaking in carb cleaner and the works we got all the rust off and the jet was plugged. I suppose half of it is still in the bottom of the carb. We have always taken this jet out and replaced it when doing a rebuild on the carb and never had it break. I don't believe the threads in the hole are messed up as it twisted off pretty easily.

Well then, if this is the case, and the jet is still 'half' ...in the passage, and half out.......you need to get the other half out,....OR, if the bottom half is still in the passage, and the oriface (center hole), is still intact, you can clean it up/out, and leave the bottom half in there, (telling the next owner what is still there), and let him deal with it!!!

To get that cleaned out, properly....you should remove the whole jet, with lft.-handed drill, and pick out all the left over brass.!!! Then re-thred the passage with the right size tap!!!!!

If you do not know what the sizing is for the threds and jet.......you can email me, and I will return the info. that you will need to have before drilling.!!!!
If the drilling is NOT done properly, and or straight, you will have just ruined the bowl of the carb.......!!!!!!

NOT hard to fix that jet....just takes time and paying attention to detail!!!
