Carb tunning/mod question

Thanks, I have a pos converter. in gear is 4" neutral is 6-7"

Set it at 26-30* initial and 10-14 in the distributor and go run it. You might build up the inside edges of your slots if you did the outsides before.

Ok,What is the reasoning behind this?

30 degrees just seam crazy, but there are those that have there timing lock out at like 38 so i guess it will be ok.
New territory, ............

Did my first compression check, 175-185 psi, only one cyl was at 175
