Its fixed!!!

Well the hunting problem is finally fixed. After all the so called mechanics and dyno tuning which all came to nothing I decided it must be something simple. So I had another play with idle jets and mixtures which again came to nothing. Again I thought "simple"
There is supposed to be a hose from the air cleaner manifold to the radiator panel which I have never fitted. I found a length of heater hose and put it in place and now the G goes so well and no more hunting. Think simple!

I never dreamed it would be so simple!
