I am just helping a friend change an engine on an old Cyclemaster classic moped. We are missing the nut that holds the exhaust on and I am struggling to work out what it might be.
When I measure it up it comes up as 7/8" and the thread gauge is giving me 16TPI and I can't find anything that matches it. The 16TPI is a dead accurate form match whereas the 14TPI which I would expect for 7/8 is not.
Any ideas?
