Tecumseh Primer Bulb Crud

Here's why you never neglect to remove the primer bulb when cleaning a Tecumseh carburetor.

That's from an engine that was left outside idle for a long time. I had cleaned the carburetor, but I hadn't removed the primer bulb. I imagine the crud may be condensation leavings of some sort.

Anyway, the engine was hard-starting, and the primer bulb felt mushy. I cleaned away the crud, replaced the primer bulb and the hard-starting was gone.
