Log splitter would not run
This was the first carburetor diaphragm I found on internet. A friend looked and found one cheaper, with more parts and free shipping. This part repaired the carb and I can get the wood split

I soaked the carb in cleaner, ringed it off and blew out the ports and installed the new parts. The diaphragm was the main culprit but a new spark plug helped too.

Found my grandfather's old plow under a pile of scrap metal while clearing out my dad's barn. The 5 hp implement was on its side in the dirt and was last used 40 years or more.

During carb disassembly, noticed the diaphragm 'flap' was contorted - not making good seal.

Carb diaphragm replaced easily (5 screws on side of carb)..
Jet needle then needed adjustment (trial-and-error to get most power).
Blade cable was a direct replacement of OEM part -- very easy.
Now my mower is as good as new.
