My TR3 is running a bit rough, but not consistently, which is giving me trouble trying to figure out where to go first.
It seems to be running rough when cold, particularly when accelerating under load. It is rough at lower RPM's and less so if I "get on it" a bit. So my initial tought was that it was running rich. The plugs are dry and brownish tan which I think look pretty good.
The car does not necessarily get smoother as it warms up, although it will run smoothly at times. Last night, for example, I took my to dance, and it ran rough on the trip there, but on the retun it ran pretty smooth.
However, near the end of the return trip, it ran very rough, even at constant speed (35-40 mph). It sounded more like a misfiring engine (perhaps a bad plug / wire / point?).
Anyway, I was think of adjusting the carbs (which I am probably not even qualified to that), but have always heard that the carb adjustment should be the last thing looked after ignition, timing, etc.
Lastly, jut to prove how confused I am, I even thought that maybe it was running lean (vs. rich), like maybe the filter was dirty, or something like that.
I guess the bottom line is the car is intermittently running rough whether it is hot or cold.
Anyone have any thoughts?
