[Healeys] Missing under Load

[Oudesluys]

Two things,
You see sparks at no. 6 plug lead near the distr. cap. NOT GOOD.
You also mention that the petrol looks cloudy. Could be contaminated 
with water, dirt, diesel, to much alcohol/ethanol. Some older tank 
coatings do not like alcohol/ethanol and dissolve/react. Drain and fill 
up at a petrol station with a high turnover.
Also check if the petrol pump delivers enough pressure and volume.
