[TR] Travel and tuning question

[DAVID MASSEY]

 I drove my TR6 (CD175 Zenith/Strombergs) from St. Louis (alt 600 ft) to Breckenridge (10,000 ft) and then up Pike's Peak (14, 010) and the only issue I had was the car was not too willing to idle at 14,000 ft.  I'm sure it wasn't optimal but it worked well enough for the short trip (VTR).

Hi all,
This coming summer my wife and I are planning a fairly long trip in my TR4A  leaving from Cincinnati, Ohio (altitude approximately 500’). Our first destination is going to be Colorado Springs, Co. to drive up Pikes Peak (altitude approximately 14,115’). Then north to Mt. Rushmore (altitude approximately 5,700’), then north to drive through Yellowstone national park (altitude approximately 9,200’). That’s going to be quite a swing in altitude and I am wondering if I will have to occasionally tune the SU HS-6 carbs? Has anyone on the list done a similar drive? If so, how did your Triumph run and what did you have to adjust?
Thanks in advance!
