Triumph TR6 - Exhaust questions
|I think I may have an endless number of questions. My exhaust was tested when I got the 71TR6, and it was running a little rich, or so the guy claimed, but not horrible; no other issues. Compression was pretty good. Oil pressure is actually, to me, a little too high. Anyway, after a tune up and carb adjustment, the car smells like it is running too rich or something. The exhaust pipes have a lot of black soot after very few miles, which I think means it is running too rich. And, until it gets nice and warmed up, it runs a little uneven at the lower end of the rpms. I have seen some smoke at a stoplight today, at idle, but not real bad. There is usually no smoke, or so little I can't see it, in my garage or drive, but it smells to me like it is too rich or something. The engine runs cool, etc.|
Is this likely a carb problem with too much fuel being burned? Or is it a major issue? It has been a little over two weeks since I got the car back from the overpriced british/jag guy and he told me to bring it back after about a month to check on the carbs (at no additional charge).
|It sounds like it could be a running rich. The easiest way is to pull a spark plug from the front & back 3 cylinders and look at the center electrode insulator. White is too lean, black is too rich. The TR6 runs best at slightly rich conditions - a brownish plug vs the standard "tan". If you find black plugs tell the mechanic when you return for the freebie adjustment.|
|John, can we assume your air filters are clean - sometimes the obvious is missed. Peter|
|Oh, and check your choke cables, be sure the chokes are all the way OFF. Peter|
