Thank you Tim. I'm waiting to get a timing light to go over everything.
I'll try 25*btdc at 4000 rpm, see what it shows at idle and take it from there.
Meanwhile the car is running quite nice at whatever it is so I was probably wrong when I said the timing was 20* btdc at idle.
I'll just have to confirm what it is.
Ill keep you informed.
