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,
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.
