engine surge

Well my problem apart from water in the gas ended up to be a coil stuffing out and overheating the ignition wire, my only remaining problem is an ocassional engine surge usually underload not there all the time but seems to be when engine is hot, apart from checking all the electrics and re-adjusting the gap in one set of points in the mallory I have cleaned fuel filters and adjusted carb floats, is there something I have missed?

Re: engine surge

I would suggest take a sample of fuel in a jar and let it set to see what settles out.
Another suggestion is to increase initial timing alittle. You can always double the book value.

Re: engine surge

Hi my friend thanks for that, have done the petrol sample thing appears clear and timing is set at 2-4 degrees above normal tending to lean towards maybe electrian may have slightly fouled a plug owing to the fact that he's not used to the car and inital start up habits.

Re: engine surge

Vacuum advance? Try pinching it off and see what happens.
