I changed the points when i first got the car started, back last year. They've been changed again and yes the condensor was done at the same time.
I checked the points gap, they were fine. I've stripped the carb and rebuilt it, everything seems to be fine, enough fuel etc.
The coil is producing 6.5kv, to me this sounds a little low, is this right?
As far as i can tell, mechanically the car is fine, i know nothing about electronics, and this sounds like an electrical fault to me.
