Hi everyone.
I have problems with the way the car runs. I have got the idle speed set at about 1,000 revs (based on dash tachometer which I understand may be inaccurate) because below this level the car hesitates and splutters when accelerating from rest. Car currently accelerates fine, but then trying to cruise at say 30 m.p.h. the car is " jerky" rather than smooth running. Before touching the carbs advice seems to be check plugs, points & timing. However, just watched an MSD video on YouTube about setting the timing and those cheery chaps said that you adjust timing at idle and that it then changes as you accelerate (you will have guessed by now I'm pretty "green" when it comes to things mechanical!). So..does it make sense to check the timing at the current excessive tick over rate as part of my elimination of causes other than the carbs? I have also read that mysterious "weights" start to deploy above the normal idle speed so again is it correct to set the timing when those things are doing their stuff? All advice greatly appreciated as today is yet another in the glorious long hot summer we're having here so I'm keen to crack on with trying to improve matters. Thks.
