I haven't had my '74 TR6 very long. I had a good carburetor guy (that knows
Triumph twin carbs) adjust the carburetors and it was running pretty good.
It was running pretty good but had the slightest miss. He suggested that I
adjust the valves. I did and a few needed adjusting and it ran better than
ever. We took a trip (appx 400 miles total) and it generally ran pretty
good but did develop an idling problem. When you would come down from top
gear for a stoplight, etc, it would either idle fine or drop off and not
want to idle at all. When you would get it settled down it could sit there
and idle fine but it didn't like to come down in revs and idle. We went on
a rally today (appx 200 miles total) and the idling problem is now pretty
much all the time and the carburetors seemed to load up at lower revs
(starting out from a stop) but clear around 2500 rpm and fine for cruising.
Also on backing off (not a lot of pressure) it would occasionally backfire.
On the backfire, I would suspect timing but it has run so good with this
same timing. On the idle problem, I originally suspected the linkage but
the more I look and the more I read on this board the more I suspect the
smog stuff. Most all of the smog stuff is still on and since it originally
was running good I was in no hurry to rip all the smog stuff off. I do plan
to have it all off eventually. As to the problem that seems to be carbs
loading up, is it possible that it is a fuel pump or fuel filter or even a
sort of vapor lock problem (seems like too cool a weather to even consider
this). Or maybe the smog stuff is my problem all together.
Any thoughts would be greatly appreciated, Jim
