[TR] TR6 ZS won'y idle

Was this after it had died on it's own?  Sounds like too much fuel rather
than too little.  Any chance your fuel pump is making too much pressure?
Did the rebuilder use Grose Jets?

Are the valves set per the specs for the cam?  Many aftermarket cams take
more lash than the stock cam; and lash too tight can cause strange idle
problems.
