It is what it is. As my sister told me "getting old isn't for sissies".
I suppose it could be worse.

Been doing it for years also.Just makes small pits a bit less conspicuous after a complete cleanup like Greg has done is what I’ve found.His look great.No scientific answer why either.![]()
So, do I need a .5mm drill for the hole?View attachment 258714
I hate to be a wet sock, but I'm pretty sure the #60 bit was WAY too big.
I tested the orifice with a #71 bit, and even it was too big. I couldn't further easily do testing with my micro-bits because #72 and smaller bits aren't long enough.
I have always used a single strand of copper wire, about the equivalent thickness of a #79 bit, to clean out choke orifices. It takes repeated stabbing to find the actual orifice -- first, the pick-up tube passage necks down at the brass fitting, then it necks down again at the actual orifice. I tried to show what I think is happening in the above drawing. The copper wire will want to hang up at the first neck-down. Once you finally find the actual orifice, it helps if you bend the copper wire into a sort of brace and bit so that you can employ a drilling motion as you try to poke at and clear out the orifice. This is all done while the pick-up hole is filled with MEK.
I have done this many, many, many times. I can usually clear a choke orifice in 5-20 minutes, depending on how badly plugged it is.
I haven't had to clear one since buying my ultrasonic cleaner, but I'm going to try it next time. I will fill a jar that is large enough to hold the float bowl with MEK, and then put the jar and bowl in the ultrasonic cleaner water bath.
Well, that's what GLJ did (#60 drill bit), and it seems to have worker for him, but I still suggest poking with a thin single strand of thin copper wire as shown in my picture, post #38, with some solvent in the hole, and some patience. Also read Gary's post #39.So, do I need a .5mm drill for the hole?
You reminded me I have been remiss with this thread I didn't post pics when I got done. I'll fix that.POST UP PICS!
I did work for me, it does make the chock richer. I'm still experimenting with how much chock to give it when cold. It starts on full chock but you have to go to 1/2 chock pretty quickly.So, do I need a .5mm drill for the hole?
I need to get some of those needle tips. I had an XJ650 carb that has a TINI TINY jet in the bowl that one of the 4 was clogged. Finally got it out with an acupuncture needle.As I mentioned earlier (page 2, post #40), I've never needed to poke the choke jet to clear it. Those long needle tips for your blowgun work every time.

Where do you buy an air gun with such tips? I think I need to get one.Yes, anyone who cleans carbs should have a set, along with that tapered rubber tip. But there's places the rubber tip won't get into, or can't be made to seal, and that's where these needle tips come into play. Find the size that will fit down into that step where the choke jet is and you get a terrific blast of air directly into the jet. Like I said, I've never needed to poke one clear, this very high pressure air blast has always done the trick.
All you really need are the tips. They'll thread into most any blowgun. Try Amazon?

No issues with it. Runs as well as it ever did.Nice. You came out ahead, regardless of any issues with the XS2.
