Priming Bulb Replacement Help - 4HP Briggs

I have a 4HP B&S Model 10A902; Type 2139 E1; Code 99042255

I noticed I had a small hole in the Priming Bulb. How do you replace that part and typically how much does it cost for the part? Thanks for all your help. Please provide link or good instructions.

One of the small engine guys should be along but I'll try some basic info. Generally the primer bulb on a small engine is pretty inexpensive and easy to change; I think typically one or two small screws and then there'll be a small rubber tube on the back. Some primer bulbs have a small hole in them, but I'm assuming you mean some other hole that is preventing proper operation.


Measure it with a micrometer; cut it with an ax.

Looks maybe even easier than I thought. Here's what the replacement bulb looks like:

Briggs and Stratton Replacement Fuel Filters, Lines, Parts - PRIMER BULB 120178

Not sure exactly how the bulb comes off, but I'm guessing the little ring in the picture is a retainer.

There are two tabs, one on either side that click into notches in the bore where the primer bulb goes. Push these in with a flat blade screwdriver and pull out on the primer with a pair of pliers. It will pop out. Put the plastic ring with the tabs onto the new bulb and press it in with a socket that fits over the bulb and will push squarely on the retainer ring until the tabs click back into their notches.
