I just finished rebuilding the carburetor on my 58 W300M. It runs a little better now but still wants to stall at idle. It also backfires through the intake manifold at the lower rpm's. The mixture screw doesn't seem to do anything when turned either way. Close the choke a little and it runs better but then the rpm's come up a little.
One other detail is that the vacuum tube at the rear corner of the intake manifold is disconnected and is just sucking in air. I've thought to close that off or reconnect the vacuum tube but haven't tried it yet.
Regular T137 230 engine with Carter E7T2 carburetor which is stock according to Clint Dixon's page. 20 - 25 degrees outside air temperature. I don't recall it acting like this last summer.
Any ideas?
