Over Heating and lack of engine power

[K. Efe Egilmez]

Hi,

Its an 90 Quattro (90 Model), somehoe engine is lacking down in power, so
the cooling system is really heating up. I've checked the radiator and its
circuitry but no luck. As a plus, I have got the crank readjusted to gain
power via the advance 16 degrees), but again no luck...

I'd be grateful if someone could help me out.

Regards,
