Flaring the end of the low speed jet has been suggested in the past. I typically don't have problems with the jet seating when flared with a blunt ice pick. Have even used a think coat of solder on the tip and only occasionally found any benefit for a sure air tight fit.
I was reading the Shop Manual and it sounds like if the Low speed jet was installed new, they had you remove it to make sure it had a "bearing" taper on the end of it. If it did, sounds like it was good to reinstall.
On another note, I just found the metering rod adjustment gauge on ebay and got it for $24, looking forward to using this to make sure the metering rod is sync'd up properly after my rebuild.
Hopefully I purchased the right one, its the T109-25
Both slightly flaring the end of a used low speed jet to make it seal, and using blue loctite instead of the copper washers were taught to me by the Headmaster of the Carter Carburetor School. Have used both for decades with no problems. Carter Sales Division suggested not reusing the low speed jet because they put new low speed jets in their carburetor kits, and of course, wanted to sell the kits.
For those that want to use the copper washers, I have no problem with that, and include them in our rebuilding kits; but I don't use them.
I greatly appreciate your input. I will keep everyone informed with pictures and hopefully a nice video of the rebuild. Now I just need to find the time to get this done.
Great news!
