These carbs are freshly rebuilt Ztherapy HS6's. The heat shield is there as it should be. Although I have thought of rigging up a double shield with some sheet metal, SS hardware, and spacers attached to the bottom of the OEM-style shield. When I track down a spare shield I may give that a try.

In any case the car starts fine at temperature now and the only difference is the OEM valves over the Grose Jets.

The thing that makes me suspect the Grose is the bleed-down when testing with the handy Mighty-Vac. The OEM held vacuum.

I am not a stockholder in SU nor do I have any affiliation with same. I'll allow that my methods aren't super scientific, I'm basing this on observation and my curiousity is way down now that its starting when I want it to.

The info about the interior of the float bowls is intriguing. Even though these are rebuilt the inside of the bowls aren't perfect. I wasn't too concerned but maybe that had something to do with it.

In any case, the 122 has many more problems that need to be attended to. I'm way behind schedule and the taxman has unfortunately taketh away. Good thing sanding doesn't cost much.

The quest continues...
