I've heard so many people badmouth Strombergs, and until 1997,
I was one of them!

My 74 TR6 had the usual (plus more) Stromberg problems.  Couldn't
pass CA smog, popped and f**rted on trailing throttle, irregular
idle,  choke was unpredictable, ran differently in humid weather,
blah, blah, blah.

I took over the maintenance on my TR6 in 1995 after spending
mucho $$$ and never having it run right.  I joined the Triumph
email list (thanks Mark!) and learned that I could take care of the
car myself.

And did so.

So in 1997, I had the throttle shafts on the Strombergs rebushed,
rebuilt the carbs myself, and put them back on the never-opened
80,000+ mile motor.

What a revelation.

Smooth idle, eagerly spun to 6,000 rpm, started and ran like a charm,
regardless of weather.  Most people thought it was a rebuilt motor.

The dyno chart at should attest
that this tired stock motor ran quite well.

I doubt if the SUs would add anything except to a dedicated race motor,
where the versatility, broad spectrum of tuning options, and relative
insensitivity to weather would favor the SUs.

Give the Strombergs a chance, and get them rebushed and rebuilt.  If it
still does not turn your crank, then try the SUs.  Its only money.
