Looking for 72 up .143/.147/149 factory jets that are
not redrilled but stock size.

I have been drilling mine out for 50 years and I would like to
try some undrilled ones as I can only drill but can not change the approach
angle which might make a difference.

I will pay a good price.

John, I use "Ninja Fuel Systems" for a lot of my carburetor needs. They have this listed. I know those aren't the jet sizes you need, but you might contact them and see.
THERMOQUAD TUNING KIT
 
I use them also for a lot of parts, They are
a good source of stuff although not cheap.

Thank you Sir!
 
John this is what I have.

.149/.143
Found new Secondary 71 jets on Mike's Carburetor on E bay
$20 each. Ouch.

Only thing that i}I would use in the kits are the 143/149 Secondary jets.
I make my own needle and seats which are more high flow than factory and
source my own primary jets which are way smaller as I have no need for metering rods
and do not use them = thus much smaller jet size.

I bought a bunch of them and while their Web Site said $20 each =
It was actually $20 PAIR when arrived. That is actually very fair as they
are impossible to find.
That was welcome news!
Still in search of 143 and particularly 149 72 up jets.
