1967 230S Vacuum Problem??
Thank you in advance for looking. I'm new to this.
I have a 1967 230S fintail with, I think, a vacuum problem.
When the engine is cold, all is fine. When the engine warms up, the problem starts.
I can be in park and increase the RPMs fine.
When I put on the brakes OR put it in a gear, it dies.
I seem to have a good vacuum when I unhook the vacuum hose from the brake booster. I have adjusted the idle speed, checked the timing, rebuilt the Zenith carbs. No luck.
I would appreciate any advice. Thank you.
