Oil in Carb. What gives?
I am bringing a '97 FLSTC back from the grave. Just rebuilt the carb and went for a test ride. It runs perfect. However, the carb overflow drain tube puked a couple of drops of oil. What gives? Does this mean I'm burning an oil/gas mixture now? I have not pulled the plugs yet to look.

Reroute your head breather out to atmosphere and everything will be fine.

I understand the concept of what you said. The breather circuit goes into the air filter bracket. I'm scratching my head.....if too much oil/vapor goes into the air filter, could it then travel back into the carb as an air/oil mixture? As a test I may disconnect the breather hose at the air filter bracket and vent to ground. Is my reasoning sound?
