Waxstat carburetors seemed like a good idea.  Use one mixture when the engine is cold, then have a temperature sensitive adjuster change the mixture once the motor warmed up.  Sounds rather modern, frankly.  In real life, these SU’s with waxstats didn’t execute so well.  So, Chip is converting them and removing the waxstats.  To get philosophical, your humble webmaster, who is no mechanical genius, has never opposed a simple manual choke and wonders exactly why they fell out of favor.

On the other side of the shop, Dean has been assembling this TR4 engine for a customer’s car.  I’ll try to get another picture when it’s all completed.  Stay tuned.
