The pencil lead in my MMI Exchanger would not come and broke off
leaving a wire core which broke off when trying to remove rest of zinc
I removed rest of zinc using flat screwdrivers to punch thru zinc
and ream it mostly free of zinc. then attempted to install new pencil
lead, but the bronze threads of the cap peeled off. The paassage
appears to have threads blocked with remains of old zinc and possibly
flattened from reaming with screwdriver. I bought a 3/8 npt tap
from Harbor Freight. I can't use torch due to proximity of
Fuel separator.
It was also suggested to not use tap as it could cut different threads
I bought a steel or cast plumbing plug of proper size as well.
Has anyone seen these weird Pencil Leads with a wire core?
Suggestions on how to proceed appreciated
