[FC] help w/vacuum leaks

[corvanatics@corvair.org]

Hi All,

input and suggestions would be appreciated

backgroup:
'64 greenbrier 110 4-speed 60k original miles

this is my daily driver, recently started stalling after warmed up.  checked and fixed multiple vacuum leaks and plastic vauum choke controls (shaft holds when depressed and hole covered)

ok, van ran fine, however when i started driving home in afternoon it started stalling in heavy city trafiic.  this time, it started being able to idle again after being driven on highway @70-75 for 30-40 minutes.  before repairing vacuum leaks, it would not start idling again

about the only thing that has not been replaced are pcv value (will replace today) and throttle shafts

also planning on trying to readjust the carbs today for the first time, have unisynce, service manuals, and other mtls

if anyone has advice on this problem it would be most appreciated,

also, can i hook up a vacuum gauge somewhere to check vacuum, if so where and what should gauge read

thanks for everyones help and assitance
