1963 AC evaporator core leaking?
Hi all,Again I have issues with my AC system. Had it refilled recently but within a few days the system was empty again. The AC mechanic added tracer fluid to check for leaks, but there are no visible leaks anywhere. I’m starting to think it’s the evaporator core as this is the only place that can’t be checked.From your experience, how likely is it that the evaporator core is leaking?And how easy (or not) is it to replace the core?See More

In the fall and winter months on a cold start, the car starts awful and wants to die until it warms up. I have to keep my foot on the throttle until it warms up or it will idle just terrible and try to die. Once it’s warm, it runs fantastic! Whats going on here? I was thinking of removing the…

Loud air moving sound within carb with cleaner removed
Posted by Dave Fehrle on March 23, 2024 at 3:23pm 8 Comments 1 Like
While checking my Carter carb with engine running, I took the air cleaner off and there was a very loud hissing sound of air. I placed a piece of paper over the carb and it didn’t move up or down, is this normal?
