LOL I should have read all the posts first. You can use either UNC or UNF. Whichever you can get. Just the tap that matches the set screws you can get. The thread pitch doesn’t really matter.
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.
