Silicon Leads

Recently fitted a new coil which is the screw in type that has a small copper disc/washer that holds the HT lead. In the old days you'd take the copper core of the HT lead and wrap it a few times around this washer which was then held in tight by the screw in cap of the coil.
Now with Silicon leads you have a soft inner core which doesn't wrap around. Any suggestions on how to secure the soft silicon core tto the washer so the HT leads is nice and firm?

You need the copper leads with the washer, screw coil and dizzy cap fittings. The other leads, silicon and carbon core are for push fit coils and dizzy caps with a brass end clamped around the HT lead or side entry grub screw clamp dizzy caps which will take all leads.

You could try shoving a bit of the copper wire up the centre of the new leads - but really won't be as secure as it would be with good old copper core leads!

personally i would either junk the coil or the leads and get a new set or copper leads from holdens (or other suppliers) or a new coil from halfords with the push fitting.
They really are not able to be mixed and matched, its either one or the other

The Dizzy cap is the type with screw in connectors so I think all is fine at that end. I think I might have to go back to a push in type coil, or revert to a copper core HT cable just for the coil-Dizzy bit.

Copper core HT leads are more reliable as long as you have supressor plug caps. You just need to make sure that the brass cap clamps around the HT lead and traps the exposed copper wires securely and then you can use the push fit coil.

Well she died on me totday in traffic - absolutely no spark. Managed to get her going again by fiddling with the HT lead so it would appear this was the problem.
On getting home here's what I did. Stripped back to a nice long length of the silicon core, threaded the core through the washer and then taped it back to the outside of the HT lead. This formed a nice strong connection which was then secured by the screw in plug on the coil. Then to be sure I put a push on type rubber boot over the top of the screw in connector and then popped a cable tie tightly around the boot. I don't think that HT lead is going anywhere........
