[TR] Rebuilding SU HS-6 carbs

Dave,
You might be better off send the black bits to a plater and have them black
oxide plated, not as expensive as chrome and will take care of your rust
concerns.

Subject: [TR] Rebuilding SU HS-6 carbs

Hi List,
I spent the day starting the rebuild of the HS-6 carbs on my TR4A. I have
one apart and pretty much cleaned up. I have to send both of them off to get
the throttle shafts rebushed and I am thinking about replacing the
butterflies which have some type of anti-runon vavle in them with straight
butterflies.
Those valves almost completely block half of the throttle area.
One thing I wanted to ask the list was that I am also considering getting
either the Eastwood or Caswell  metal blackening kit to coat all the screws,
springs, and brackets so they don't rust. Has anybody used either of these
kits to coat bare steel parts?
I ended up cleaning all the parts ultrasonically first, then the outside
with glass beads, and finally using walnut shells. The final finish looks
pretty good. I am not a big fan of the polished look.

I updated my website with the progress so far if anybody is interested..

Go to Check my progress. There is a link there to the carb rebuilding page.

I hope to get the other carb apart and cleaned tomorrow.
