Briggs 145 series 4. Backfired on shutdown, now wont start


LawnSite Member
Hi - I have a briggs 145 mounted to a Countax C350H. Spent about an hour mowing - worked fine. Shut down and there was a backfire. Went to start up about 20 mins later and it just turns over.
There is spark and fuel to the carb bowl - removed carb and gave it a clean. Still nothing.
Checked compression - 110psi.

The backfire is a concern as it was working fine before this. Any suggestions on where to look next ?

Did you try a splash of fuel down the carb intake? Starting fluid? If it runs and then stalls it's a fuel problem. Do you have an inline spark tester? Should be something simple if it was running when you shut it off. Good luck.
