TD Speedo Problem

[JHoltslag@aol.com]

MG'ers,

   I rolled my TD restoration out of the garage today for the first time  
and putted around the neighborhood.  It didn't explode or catch on fire
but I did notice the speedo doesn't work.  It goes up to about 30 and falls 
back to zero only to rise up to 30 and then back to zero..over and over..  
Does this sound like something simple to fix or does it sound like I need
to send it to be rebuilt?    Joe "God a TD doesn't shift like a M**ta*!
