The PROS and CONS of my new engine: PROS: Small Engine Warehouse (SEW) delivered the new Briggs and Stratton 44T977-0035 engine so fast that it was shipped here in 3 days! The sale was pretty smooth. The prices were very affordable. The new engine also has plenty of power to cut my lawn. CONS: Better support on components could be mentioned on the SEW website as to what each engine could need to replace another engine. A better representation of wiring diagrams would also be helpful as this took an enormous amount of time and research to find out what wiring went where. I had to create my own wiring diagram to understand fully as a DIY guy to how to get the engine running properly. Greater emphasis on getting the correct shaft length would also be very helpful for DIY. My previous Kohler Command had a built-in solenoid, but I had to guess on my own that the B&S engine needed a separate 3-post solenoid. Nothing in their documentation mentions this or on the SEW website. Lastly, the Kohler Command manual of 20 years ago is complete and extremely helpful. The manual for the B&S is useless regarding any practical or useful info. After finally getting the engine at starting point, the engine, however, has been hard to start (it only has 6 hours on the motor). It does not crank quickly for some reason. I purchased a new battery). I have had to start by spraying starting-fluid in the carb to get it started. Today that worked but then the engine cut out a few hundred feet from my home and would not restart even with more starting fluid. My gas is fairly fresh and the choke fully works. Is the new fuel pump defective? The oil is level. What gives??
