I recently purchased a 1979 450slc. It runs very well but does have a few minor glitches. It takes a few seconds to start when cold. It is very consistent about how long it takes to fire up depending on how cold the engine is. Also the engine bogs down if you give it a small amount of throttle. As long as you push the pedal past the first inch or so then it runs fine but I have a feeling these symptoms are related. Beyond routine maintenance does anyone have an idea what might cause this?
Thanks in advance.
