1.7 carb tec-tec noise when hot :
I finished assembling the engine on my series 2 1.7 QV .
I'm currently having a problem :
When i start it, cold, it starts faster then the 156, it keeps running as smooth as it can be not fully tunned yet, but as it gets hotter, it doesnt over heat, it starts making a tec-tec noise, diferent from the tic-tic from the hidraulic tappets .
It has new everything, including oil filters, etc...
What could it be ?
Any ideas ?
BTW, which flywheel mark is the correct one to use to adjust timming ?
The hole, the "higher" round spot, or the vertical mark ?
