My 1955 M38A1 is putting off a foul odor, much like a sewer(sulfer type smell). This occurs after driving it about 15 minutes or so. It leaks oil and is currently missing like crazy. Could the smell be from the oil or from the gas not burning correctly? It is a terrible odor that nearly makes me sick. Any suggestions?

Modern unleaded gas produces the sulpher smell. A really bad sulpher smell with missing indicates too rich. Check float level, float valve, and both vacuum diaphragms (accelerator pump and metering rod).

Thanks, but what exactly should I look for or adjust. I did rebuild the carb.... new kit. The level of the float? There are only two adjustment screws on the outside. What else can I adjust?

This is what you need to check.

I'm curious as to which carb you're running- ys or wo.
(i hope you took the earlier wise cracks in the fun they were intended).
