I had the same problem with my TR 7 Z-S's and from what I hear from  
others, it's always the rear carb.  It doesn't take much crud in the jet to  
prevent it from shutting off the fuel.  I'd look there again.

List-


I need your collective help.

I have a  relatively new restoration of a TR 250 and the carbs were
rebuilt in the  Summer of 2008. Since then, the car has run relatively
care  free.

However, after a few month lay off, I tried driving it in March,  only to
smell a strong gas smell once started. I left the car running,  popped
the hood and determined gas was pouring out of the float bowl of  the
rear carburetor.

Last night, a friend and I tore down the carbs  and found a small amount
of dirt in the rear carb, installed Grose jets in  both reassembled them
and the same thing occurred in the rear carb only. We  then removed the
carbs, inspected both and adjusted the float to 11/16ths as  the rebuild
kit suggested. Same result. We are baffled about why the rear  carb is
overflowing gas from the rear carburetor. Any ideas of what we do  next?

Many thanks in advance.
