Thanks Shane.....

That's a breathe of fresh air in the Stromberg Barn of Bad Smells.

Sometime in the 70s I rebushed my worn shafts and rebuilt these TR4A Z-S. The 
car was dismantle and I set the carbs on the shelf.  

30 years later they have resided on my TR4 racer for 14 years and seem to 
perform quite well.
