Tunnel ram or no tunnel ram...

I cant get any brass set screws here. I found some Chinese online shop that sells them 100 each size but not sure about correct depths. I’d prefer to use what’s normally used.
Do you think i can buy drill bits off ebay and send them to you so you can make a package with everything meaning drill bits and set screws?
6/32 unc tap set is 9$
8/32 unc tap set is 8$
10/32 unf tap set is 11$
The 10/32 should be unf correct?

I will try removing IFR from top of channels to see if that will cause rich part throttle condition.


Absolutely I will do that for you. You can use the 10-32 UNF. It will work fine. Just get the same thread set screws and you’ll be fine.
