A primer bulb is important because it helps to fill the carburetor with the correct amount of fuel. You may need to fix or replace your primer bulb if: It is not creating proper suction/pressure. It has a crack in it.
There are different types of gasoline primer bulbs, all of which contain various types of valves inside. Sometimes these bulbs become so hard it`s difficult to squeeze them; sometimes even though you can squeeze them, they pump poorly, if at all.
When the outboard is sucking fuel out of the tank, it creates a vacuum. Sounds like something was blocking air from entering the vacuum that`s created. Maybe the rough waves got water and debris into your fuel tank vent and the vacuum sucked all of the air out collapsing the bulb.
To provide an adequate fuel/air mixture, gas may be placed directly into the carburetor to prime the engine. Priming carburetors is a dangerous and unnecessary practice and can produce explosion or fire!
Use a Primer

In general, what you`re painting determines how to paint. “Primers are made to adhere better and/or seal a surface better,” he says, “so normally, we`d recommend a primer first, to make sure that surface is sealed, and that it will adhere properly and seal the surface to prepare it for paint.”

Without a coat of primer, you`re looking at a splotchy paint job. Applying primer prior to painting drywall will give your finished wall an even, clean look.
Hoffman explained with a blown primer, you`ll generally see a lot of soot or powder residue around the primer pocket. A more definitive determination is to see if the primer will fit back into its pocket. In the case of a dropped primer, it won`t because the case didn`t expand due to high pressure.
ANSWER: The primer bulb, which is located in the fuel line between the gas tank and the engine, is used to fill the carburetor with fuel when the engine is started cold. The rubber bulb resembles an oblong ball. Inside the bulb are two valves that open and close.
Once the engine is running, the feed pump produces a suction that draws fuel through the bulb valves. Without the fuel coming in through the bulb, this feed pump cannot work properly. The use of the primer bulb is therefore crucial.

Have a craftsman 16″ chain saw 358.360260. Could not initially get it started after it had sat for a couple years with fuel stabilizer in it. When I went to use it the fuel had all evaporated and the fuel pick line was rotted. I replaced that with some difficulty but finally got it on. Saw still wouldn’t start. Replaced the fuel filter. Still wouldn’t start. Pulled the carb apart and cleaned and recleaned everything. Diaphragms were good and I didn’t adjust any of the mixture screws because as I said it ran fine before storage. Non of the carb passages were clogged. Fresh gas 40:1, good spark plug and good spark. Airfilter is good. Engine has maybe about 4 hours of total run time on it. It’s a ZAMA (?) carb. It will run for about 30 seconds when I manually prime it by pouring a small amount of fuel directly though the carb. When I was disassembling the carb the vent hose that goes back into the fuel tank seemed to have a small out of ?substance? in it which I cleaned out. It was right at the end the of the hose that goes back into the fuel tank and not up by the carb. It didn’t appear to be like your typical gummy deposits/varnish though. I hope it wasn?t some type of spongy check valve stuff that is supposed to be in there. That might explain some of my problems. Anyway, I also can not seem to get the primer bulb to fill. When I open the fuel tank, look in side and depress the primer bulb, air bubbles come out of the fuel filter. But when I let the bulb reexpand there’s no fuel that gets sucked up the hose. I can however seem to fill the primer bulb when the fuel tank is full and the chainsaw is laying on it?s pull cord side and the bulb is depressed a bunch of times. The saw will also start and run again for about 15 seconds then die. It’s definitely not getting/fuel and probably running out . Thanks.
