Minor setback?! Pilot Mixture Screws

Having a minor setback with carbs. As I was cleaning the carbs, I found that the 2 of the pilot mixture screws are totally stripped out. I hope and pray I can extract them with minimal damage. Any suggestions would be appreciated. Thx

 

Hi Jdb,
I fixed one in my Hitachi 32mm carbs... it wasn't pretty!

It started off that I got a really, really tiny ezy out and drilled a hole in the mixture screw with the intention of pulling it out...

When that failed...

I ended up drilling it out as far as I could without hitting the thread in the carb and then a Dentist pick with a lot of messing around was used to collapse the mixture screw into shards (brass is brittle) and ... then
finally I used a tap from chacal to clean out the threads/re-thread them and put in stainless steel mixture screws, also from chacal.

All of this was done with the carbs completely stripped and originally I tried heating the carb body up also, with CRC flushed all over the area.

You wouldn't know I did it now. But it is something that could end up badly if you don't take your time.

Good luck!

 

Thanks CDS for the info! I made up my mind to go slow with this bike so if it takes two years to get my bobber the way I want it. That's fine. I know I wouldn't have a chance without the help from this forum. Nobody up here in the mountains has a XJ. Most of the older bikes are harley's or honda Cb's.

 

Got the screws out without damaging my carb body! Yes!

 

Well, carb body is totally screwed!!!!!! Guess I'll have to find another one. Awesome

 

Ouch!
That sucks, sorry to hear it didn't work out.

 

I have some extra carbs - I'm sure we can work something out if you need one. Just PM me and let me know.
