Primer bulb

[Denis Kansier Sr.]

In all the posts I've read, everyone says they must pump up their primer bulb to start the engine, but I have never had to pump mine up and the motor always starts really quick. I'm a fan of "if it ain't broke don't fix it" but this 'soft' bulb makes me curious. Yeah, I know-curosity killed the cat.....but satisfaction brought it back. What gives with the bulb??

Driftwood...I don't have to pump mine either. However I believe it is a common problem especially with smaller engines with portable tanks, especially if you disconnect the fuel hose. Be curious what others have to say.

Pumping primer bulb until firm before starting just gives your fuel pump and carbs a sure fill before cranking over.Also if you'll do it before running engine until bulb is firm it will confirm that your float valves are seating in carb bowls.
