I have a 4 OHP Quattro Briggs & Stratton engine on my lawnmower, and
when I use the prime bulb to try to get the engine started the priming
doesn't work. I take off the top of the sort of rectangular metal box
that holds the filter, (and the filter appears to be clean), and pour
a little gasoline into the engine and the engine starts up. Can
someone tell me how to get the prime system working again? Thanks,

JD

Read the section entitled "A primer on priming" at:

The tiny tubing running to and from the primer tends to break down, loosen
up or fall off.

Thanks for your response, but I have a followup -- How do I fix it?
Do I buy a new tube or do I just clean what is there or what? Also,
is there any trick to getting to the tubing or is it obvious where I
am going. Haven't worked with this type of problem before.

The site I offered before has instructions for cleaning/repairing both
B&S and Tecumseh engines.

Look for the sections on cleaning the carburetor since this will most
likely require you to interact with the primer bulb and tube.

FYI - I had never worked on a lawn mower engine before last weekend,
but by using the instructions at this site I was able to replace the
flywheel key, which required making a tool to remove the flywheel. All
the info I needed was found at that site.
