Good video Leon! Try a bread tie wire with the paper burned off the outside. Should fit like it was made for the carb. I find that white stuff in the old Tecumseh's that I see, in the bottom bowl nut. Its something that comes out of the gasoline when it completely dries out.
Interesting fix...bravo! My typical carb fix go-to is 1) Disassemble and ultrasonic for 30 minutes 2) (Carefully) blow dry with 20 psi air 3) Reassemble with a new carb kit That normally does the job. Normally. 😆
Persistence pay off great work I learned how to work on carbs and to get them perfect the first time around from watching the channel I appreciate all that you do thanks.
Good job Leon.. i like to use tip cleaner for a torch ..i got a good collection of them from welding for the last 35 years or so . Pretty handy sometimes.. thanks for showing how to troubleshoot these saws i appreciate it
I would try a jetting drill bit set. They r pretty small and can help to open clogged holes by turning bit by hand. That's what has worked for me in past. Also good to have on hand is guitar strings from a music store. Get ones that they change and throw away
Good job not giving up on that carb. Do I remember you saying there was loctite around that main nozzle? Could that chunk you pushed out have been loctite?
It's there a small enough drill in one of those torch to cleaning sets. They come with tiny drill bits and a holder collet to twist them. Maybe for next time.
You can find an inexpensive (cost me 8.99) "Hand Drill Bits Set, Pin Vise Hand Drill, Mini Micro Drill and Twist Drills" set that goes down to 0.1 mm drill bit size that may be handy. I also have a welding tip cleaning tool that could work.
The questions is: How do these stones get in there? They can not pass through the fuel filter, and if they do they can not pass through the carb strain, and hardly even past the needle valve. So they are not coming with the fuel. Then they must come with the air, past the air filter. As the saw is idling the stone ends up at the bottom of the carburettor bore and sits just behind the throttle. Are they then sucked in through the low speed holes 2 and 3? Sucked in to the idle chamber that way, and then gets forced out through hole 1, but it is too small, and the stone gets stuck? If that is the case then it is a high risk operation to test run the saw without air filter.
The running rich may be because you put that diaphragm in with the little bit bigger nub. Remember you took out the one filed down? Maybe why it's richer than you're accustomed. Cheers

Excellent diagnosis ! Good fix 👍
Taking a little time to think about the issue lets you come back to it with a fresh approach.

Glad you can sleep tonight having solved this carb’s problem!!!

Nice test saw Leon.

Those in tank filters dissolve when fuel is left in the tank over several months and plug uo everything...

Ethanol dries to a very hard white deposit, appears similar to fine salt
I do that on all carbs when clean them. The carb clean is not enough
Ultrasonic cleaner?
