Product Description

?

The diaphragm provides a tight seal between carburetor components. Unfortunately, over time the material will wear out and it may begin to crack eventually requiring a replacement. It is an authentic item that is supplied by the original manufacturer for use with Briggs and Stratton engines that are commonly installed on lawn and garden equipment. Keep in mind this high-quality component is made of durable composite material and is sold as in a pack of two. Refer to the appropriate diagrams for your model to ensure the correct repair procedure.

I wanted a project. The previous owner said i could have it and it may need a starter? It\'s a pull start.

Step 1 Power wash and engine degreaser.

Step 2 Inspect for oil - it was almost dry. Checked for spark - good. Air filter has never been changed. Primer bulb shot. Got it to start eventually - stable enough.

Step 3 Tore down the engine cover and carburetor enough to figure only that the only service this thing has seen is gasoline. Ordered the above parts.

Step 4 Cleaned out the carburetor and the top end of the engine. Sharpened the blade and made sure the whole mower was structurally sound.

Step 5 Replaced the parts that were ordered including the missing wheel assembly. Changed the oil, fresh gas, Three primes of the primer bulb. the machine came to life on the 1st pull.

I have mowed my grass three times so far, runs great. Selling it to a friend who needs a cheap mower
