My bad! Yeah I turned it in rather than out by mistake

Yea, that's what I guessed 😊😊😊
DomP:
Short of biting the bullet and stripping it down are there any tests I can do to detect what sort of wear I might have? I think I know the answer to this one! One thought I have had, could it be a weak or intermittent spark causing the roughness and therefore the smoking/smelling rich? The HT leads are pretty rigid and the coils a bit knackered looking.
McCabe-Thiele (Ted):
My brief experience with coils is to look at where the HT leads just exit the coil if the outer insulation is cracked then they are probably part of the problem.
DomP:
I'm going to order some new ht lead and caps (plugs are new non resistor type) and do the 'Ash fix' on the coils to rule that out as a possible cause. Could the carb sync being out be enough to cause it to sound so bad? Going to get a load of airline to perform a carb sync as well and see where that leaves me, if all this doesn't solve it it is at least nothing lost and I can move on to looking at a rebuild.
