Re: 92 evinrude xp150 carb bad gas leak
You may have another issue going on. Those carbs should have the plastic bowls. Over time, the original plastic bowl mating surface distorts. Undisturbed, the original bowl gasket keeps the seal intact. Once the original gasket is replaced, new bowl gaskets can't compensate for the distortion of the bowls and they can leak. You may need to replace the plastic bowls with older aluminum ones that are dimensionally stable. If you do get into this conversion process, you will have to buy new jets for some, as the old bowls are machined for different jets. Also, the drain plugs are a different size.
