- I hope someone on the list can offer an explanation and solution to a problem I've never seen before. My TR4A is running rich withg sooty black plugs on cylinders 2 and 3, but perfect coffee with tri

- What kind of carbs? Sounds like a stuck richening device, but I don't know enough about SU's or strombergs to say. Another possibility is a very restricted exhaust, though I can't fathom how that wou

- I'm probably showing how little I know about SU carbs, but don't they have a separate cold start mixing device that feeds the center cylinders almost exclusively, or is that just on the old Jaguars.

- Old Jaguars, and some models of SU (HD8 ?), did indeed have what amounted to a separate carburetor just for cold start. Some TR7s had this too. However, Simon said he has the HS6 SUs, where the cold
