Reply To: Is this part of the carb???

Peter,

Without inspecting the hardware a definitive answer is not possible but here’s my best guess …..

There is probably an internal passage which could not be cast or machined without this access hole which must then be blanked off for the carb to function as designed.  Possibly a feed from lower in the float chamber to the choke mechanism?

We have recently overhauled the carb from Stephen Prigmore’s 1932 C4G, purchased as a non-runner.  For a “simple” carb, it had a most tortuous series of passages and galleries to get additional fuel to the choke “jets”.  Much of the route was heavily blocked and even the gasket did not have appropriate holes to join the respective passages in the two halves of the body.  It was not surprising it would not start for us and I cannot believe it could ever have run with the carb in that condition.  The one blind passage in this carb is sealed with a brass screw-in plug making access reasonably straightforward.  So, after heavens knows how many years, it’s now a runner.
