Got the 990 all oiled and greased up on linkages and all move free and easy now, even the brake works right. Was running wonderful. Then, just decides it won't start one time. Lots of spark, fuel line OK, blew into carb inlet, pulled the needle and gas runs out. This thing some days cranks all day to start, other times instant start when hitting key. I even went down and refreshed the selonoid, which had bad wire from switch and got it better. NOW, the gear went bad cranking it. Darn plastic gears on these Briggs, what is the deal??? I have seen aftermarket metal replacements but never for the 16 tooth like I always have. Why not these? And why does it seem only half the gear gets worn off and they never go full depth into flywheel? SO, off to shop for gear. I see these on epay all the time in pairs, sets of 5 and even like packs of 20, all official B and S parts. Guess I see why now.
Have a guy called on it to see in AM, and now it does t his too me. Tractor Gods Hate Me!
