Fuel Stains
 

I noticed after the past 2 flights, fuel stains on the floor under the rear engine right and lef fuel vent lines that discharge through the lower cowling below the exhaust openings. Has anyone had this problem and what was the fix?

Might be the divider valve. The fuel is probably coming from the cylinder drains. Good luck as I fought the issue for years and never did find a total fix. Is there oil mixed in the discharged fluid?

I've had this occasionally on my 1973 G model. It occurs randomly. It may happen a few times a year and then I won't see it for a year or two. I don't know if it is coincidence or not but it seems if I open and close the throttle a few times and even leave the throttle half open or so, the drip would stop. I don't know if some small pressure differential occurs that causes the drip or what but try moving the throttle a few times. It doesn't cost anything!

Let me know if it works.

Ed and Herb, thanks for the comments. Just checked this afternoon and no stains so I'll keep check and try the throttle suggestion if it reoccurs.
