To see our recommended tools and products visit our Amazon shop at We check out a John Deere 145 Mower With Briggs and Stratton V twin engine. Customer had us pick it up with a complaint that there was popping when they were running it. This popping would smooth out or stop happening when they had the blades engaged while mowing they said We check the oil and realize it has none in it so we fill it up and figure out what is going on. The loss of power is very obvious along with the popping prevalent qhen we test it to find the issue We also go over three other mowers with the same style Briggs & Stratton engine with different issue cause from being ran low on oil. We go over the full diagnosis process for each and thoughts on whether they should be repaired or replaced at that point. Like and subscribe to see more helpful videos like this one!
