Default Dubro tank stopper--mine melted

Yep--did not think it could happen. Got some trash in the carb of my 3W 24 and cleaned it out. Went to find the sorce of the problem and all sorts of things were in the tank. I thought maybe had lost my mind and used the wrong type of stopper, until I went to buy another today and it is the same-(brown in color)
CONFESSION TIME: The plane has set up for about a year and a few ounces of gas was left in the tank. When I took the tank apart the brown stopper was melted and smelled sorta like varnish--this was the stuff in the tank.
I can't remember for sure but I may have used Sta-Bil in the gas when I mixed it. Could that have done it?
Any Ideas on what happened or has this happened to you?

You're not crazy. The fact is you did nothing wrong. This problem has been around for a long time. There were a mis-colored batch of stoppers produced awhile back (three or four years ago) and they still showing up from time to time.

I too had one of these rouge stoppers in an airplane last year, went dead stick, and totaled my airplane on takeoff.....

Yep, it sure was a stopper that clogged my carb. It had disintegrated in the tank, just as yours did.

The consolation you ask? Dubro said they were sorry about the snafu and would replace the defective stopper. The arrogance. :rolleyes There were many instances of this problem reported on the internet at the time.

That's the reaction I would expect from Great Planes, but to hear it from another manufacturer/distributor is distressing.....Maybe Great pains owns Dubro. Anyone know?

Mine went deadstick at the top of a snap--floated it on in--sorry to hear about your plane--that is a shame.
