My neighbor bought the cheapest Walmart mower. A Murray with a 4.5 Briggs and Stratton engine. I was mowing her lawn with, the air filter cover fell off (didnt see it) and I ran over it. I have called Briggs and Stratton. A B&G dealer. Everyone. I cannot get the part without the model # off this mower. I have given them EVERY # off the mower and they cannot help me. I told the dealer I WILL BRING THE FCKN MOWER TO YOU.......they said they still cannot help me. I went to walmart on Waldo Road opened the box of the same mower and still couldnt find the model #. I took that part off and held it in my hand and looked at it for a part #............I wanted so bad to just take it home. Called my brother who knows all about machinery. He said he could find the model # in 10 seconds. Or just take pics of the mower and he can find it online. We will see. Took my Honda Civic 05 to the dealer today and got the airbag replaced. They bend over backward there to make you happy about coming in there. Now I take my 05 dodge truck on Friday for the same thing to Dodge.
