The problem is most people don't have a Lathe Norm and Ironbark and if you paid someone to machine the spigot it
would cost a minimum of $30. plus the cost of another mower for the carby but it's worth doing if you have the lathe
and the carby parts already.

I don't usually call the plastic carby a LM , because I just refer to them as a G4 , the LM just stands for Late Model , so you have an early G4 and a Late Model G4.
