Thomas Middleditch: Park it in front of a troy built or briggs $ stratjunk dealer or manufacturer then set it on fire before it starts on fire while you're on it mowing. I'll never own a B & S or troy junk or mtd (mower took dump) ever again. I can build an old Harley knuckle head, throw it on an old craftsman mower and have it last longer and be much more reliable than this junk.
Travis Reid: the gas and air mixture needs to be adjusted
jim davidson: So what do you think about sea foam now? Kind of a waste of money right? You can use kerosene to do the same thing.
MrChuckell: .oo3 to .005 on both valves manual calls for .004 on both intake and exaust your exaust at .008 is opening twice the distance it should i think you need to set both vales at .004
john stra: I dont know?// When you rotate your motor with the rocker cover off... look and see how much they move. One valve moved a 1/4 the other barely moved.
Thats how i knew... oh after I spaced/ adjusted the valves. they shouldnt be real loose either. thats how you know you need to adjust them. I think they get loose with wear.
john stra: Might have been the exhaust.. i dont know. bought the cam online and it was EASY! Runs like a new mower... Just always check your oil thats probably what happened. Kids cutting the grass.
MrDanrob62: Did you replace the camshaft? and if so, how difficult was it? I have the same problem, but it is the exhaust lobe instead of the intake.
sneezie22: Thanks for this helpful information ! How often do you change your oil ? Is the worn cam a common thing on this model ?
memphis502: I fixed it myself.. pretty easy. Check out my other videos. A way to tell is take off your valve cover (if valves are gaped right) rotate engine and the valves should open and close about a 1/4 inch of movement. My Intake was not opening much. The cam lobe was worn down.
memphis502: Ok I figured it out. It was the camshaft. The intake lobe was round instead of teardrop shape.
need advice ??? 17.5 HP Briggs & Stratton Intek ohv ic not running right. Troy Built pony5
