Tomco carbs and kits got junky in the early 90s while I was in a USAF motor pool buying repair parts. Anytime carb work was required, a Tomco rebuilt and an Echlin kit would get requisitioned, then the rebuild was rebuilt and installed and tuned. Heck Tomco couln't even get the floats set right.

Pretty bad when voiding the warranty was a non issue.

(Also I learned you can overheat a 727s and TH400s enough to melt the case, but that is a story for another time.)
