Ign lead metal Shrouds

Post by R0B »

Andrew Campershack told me he always removes these as they are more trouble than they are worth. I cannot remember the reason, as it was a few years ago. Question is what their purpose in the first place.

Electromagnetic screening, in conjunction with carbon leads. In the days of AM radio it was more important.

I read about this a while ago before replacing my leads. Something about misfire /sparks jumping from the shroud to the cylinder head. I've still got mine as i don't have an issue with them.

Thanks, David.I think that was probably Andrews explanation.

That was it.
I've cured poor running on several vans by removing the shrouds. Ask chucklebus Tom. The difference on his MV was dramatic!
New leads with good insulation should be fine, only remove them if you're having problems.
