Another day, another question (or two).
I'm rebuilding my carbs for my new engine. Putting in some Sweet Sweet HRC jets and needles.
However, I find that my two sets of carbs have different size slow jets.
Picture below. Which one is the correct one?
if the picture isn't big enough, let me know and I'll upload a bigger one
Part two of my question...
Seems one of my expansion chambers got a bit munged in my stack. Only just realised how bad when I took the pipes off to drop the old engine out.
Picture below...
As you can see I tried heating then rapidly cooling a couple of the smaller dents. I only have a butane blowtorch so they didn't quite get red hot. Regardless, it didn't work.
I'm seeing the options online as:
1. 80% fill with water - freeze
2. Seal pipes and fill with compressed air, then heat the dents until they pop
3. Drill holes and physically pull or bash the dents out - weld up holes.
Opinions on the best course of action?
Edit: I'll sneak a 3rd question in quickly.....
When setting the needle for the HRC jets is the top or bottom slot number 1? (Which end do you count from?)
Thanks (again)
