Briggs Stratton 80202 gas leak

[articaine]

If you feel you need to use a sealer...
Try something that will be tolerant of gasoline ... permatex Aviation#2 or permatex right stuff.
Anything else is going to dissolve sooner or later causing all kinds of grief... today's gas has a lot of additives that will eat most things up...

Thin steel can easily warp... If you place a flat edge over the surface, how much gap do you see?

Come to think of it when I bought this thing and took it apart to service there was only one gasket between the carb and intake. That could of warped the tank.

Yeah I don't want any grief in the future. If I don't use any sealer and just use one gasket, whats the best solution? I don't think I want to spend the money for a new tank.

How much gap is there when you check with a flat edge along the mounting place? :smile:KennyV

Rivets,

Finally got around to placing 2 gaskets. It seemed to make things worse, more gas leaks out. How would a gas tank get warped?

Any suggestions? Silicone is no good?

Rivets, the 2 gaskets did not cause the increased gas leak. First time I noticed some gas seepage, but the 2nd time was after I had replaced with 2 gaskets. When I was replacing the 2 gaskets I checked the cover screws for the diaphragm and they were tight. This time when I removed the gaskets to check for any warping I noticed that the screws for the diaphragm cover were loose! I tightened them. I haven't run the mower to check for any seepage.

KennyV, the gas tank was checked with a known level plane and there was no warps in the tank.

So, my question now is should there be any leakage around from the diaphragm area from normal use? I've read somewhere, not this forum, that one should level the surface of the metal contacting the diaphragm with sand paper. B & S, specifically state do not. :confused3:

Since I've tightened it and gas should not flow out like it did, I think if there is no solution to the seepage I'll just deal with it...but I feel it's not the norm.

Ran the mower, and there is some seepage from the diaphragm cover. If there is not a solution or if it is not a big deal then I will just leave it alone. Ima retighten the screws if it leaks more.
