Recently I had 'her' '70 M1 power tuned on a chassis dyno. Gained 15hp at the wheels. It had to be done like that because the timing marks were nowhere to be seen.
Yesterday I was able to set the idle speed and idle mixture, knowing the timing was right. WHAT A DIFFERENCE!!
As soon as the idle mix was correct and in balance the idle speed shot up. I could at last get it smooth and at the correct speed. Cold idle on choke still needs a bit of attention but it is soooo close now. One problem is that the engine heats up so fast one does not have a lot of time to correct things!
In all I cannot recommend a correctly executed Power Tune highly enough.
