Briggs and Stratton Model 44N877 Type 0003G1

Pulled the carb off again to correct a bowl fuel leak. Previously someone said to check the manifold seals. The attached picture is what it looks like, no other gasket on it. Does this soft seal need replaced..., looks like it to me. I ordered the set. Always thought there should be another seal on it though.

Thanks!!!

Yes, and I would look hard at the mating surface to make sure it isn't warped. The plastic intake manifolds are known to warp in both the head mounting surfaces as well as where the carb mounts. Overtightening the carb mount screws can also warp the intake.

I've never seen a green seal on those. Appears someone did a sub with a O-ring for a AC system.. they are usually black.

I do not trust re-using the old o rings even if they look good. I leave the old o rings in place and make a paper gasket and use a light coat of permatex sealer over both faces of the gaskets.
Some kits have the flat gaskets and no o-rings.
Also notice that the plastic manifold has steel sleeves and the manifold can only be tightened so much and if the o-ring is old it may not seal It's also common for the manifold to warp The OEM are not true o rings they flat on two sides..

You say you pulled it off AGAIN. SDo you have another post/thread about running issues?

Briggs has used orange and black square seals but they have switched to the new green seals. After market ones can be black. The PN is 594209 and it is a package of 2. As Far as I know they are not interchangeable.

I only have 11 packages of them

The one shown in the picture is very heat distorted. These seals usually require replacement anytime the intake is removed.
