B & S 13.5 HP engine. Won't start, good spark,backfiring on start
Seems to be getting gas. I replaced the top part of the engine (where the gear for the starter engages) because the original one was plastic and the newer one came from a 15 HP engine, it has a metal gear ring. As best I could, I lined the new one up on the center shaft, but I'm wondering, could it be out of time. Also, is there any way to check the timing.
Other than that, is there anything else I could check?

When you replaced starter did you notice the condition of the
flywheel ring gear? My guess is the ring gear is very badly worn or somehow the positioning of the starter is such that it is off enough
that it runs into the ring inside the gear. Did you hit something in the road before this symptom started? Any chance someone tried to jack up the car and used the starter as a lifting point?
Accident? Are you sure it's your original engine? Ie they used to be very easy to change. Any other thing that would bend the mounting point on the engine? If manual transmission, try to move the engine a little by moving the car with clutch engaged.
If Automatic try to move ring gear with a tool if you can get to it.
If this action is sufficient to move the ring gear into a "good" spot
and the Starter will engage, you now know you have a few bad spots.
You did not mention the model or make..but most have a simple starting system..the starter ususally is located on the side of the engine facing up for the vertical shaft or front or back for horizontal shafts..two mounting bolts and one or two wires from switch and battery...easy to remove and replace...if you are saying spinning not engaging it is the replaceable spring loaded flywheel engage gearing on the top of the starter...the third would be bad but replaceabke selonoid that transfers the battery voyage to the starter ..just follow the starter sure back it originates at the selonoid...good luck.
I think this is going to be like an automotive starter. You will need to check 3 things. The ring gear where the starter gear cranks the engine, the starter gear that engages the ring gear, and the overrunning clutch or bendix , which is the springy part that kicks the drive gear into the ring gear. When you remove the starter from the engine, you will see the drive gear on the end of the starter that was inside the motor. The drive gear is about the diameter of a half dollar or a silver dollar. it should not be chewed up, it should look like a good gear. Inside the place where the starter attaches, you should see a ring gear, with a flashlight, and those teeth should look good and not chewed up. On the starter you removed, behind the drive gear and usually inside the starter is the bendix or overrunning clutch , which will push the drive gear into the ring gear when you crank the starter. These parts often fail every few years. Some people fix them, most people replace the whole starter. Be blessed.
The way them starters work is it is either engaged by a silonoid or a reverse plastic gear so when the starter is energized the gear comes up so. In other words u can buy a new starter or take it to a shop and have them rebuild it. If it is the plastic gear kind u can geta new gear for it
Hi, Anonymous your starter motor is not/was not the problem that dubious title goes to the starter drive/Bendix/clutch which is a separate component that is activated by the starter motor it is a mechanical gear driven part that engages the clutch pack to turn over the engine. It has an internal mechanism that allows the gear to turn in one direction and once the engine starts allows the drive gear to free spin. If gear free spins in both directions then the drive gear has failed, it is not serviceable and needs to be replaced.

The starter gears engage the bottom of the flywheel when starting the mower with the electric start if you can see that some of the teeth on the flywheel are stripped , you definitely need a new flywheel, parts diagram shows that it has a 'plastic ring' gear on the flywheel and doesn't show that the part is available seperate. Below is a picture of the assembly.
About the running condition of the mower, I would start by removing the carburetor and cleaning it, get a common twist tie and remove the outer paper so you have a bare wire, use that wire to clean out the small hole in 'brass bowl nut' located on the bottom of the carburetor, then dry out with compressed air. The diagram below also shows the carburetor.
The clonking noise I assume is the starter drive (bendix) engaging the flywheel. Could be the starter, or a bad connection on your cables from the battery to the solonoid and then to the starter. Check your ground connections from the negative side of the battery to the motor ground also. Clean all connections throughly. IF you have a tester, check the voltage to the starter terminal when it is engaged. It should be close to 12V , if it's low then work on those connections. If none of that works, make sure your motor is free to turn. Try and turn the motor pully, if you can't turn by had, then carefully try to turn slightly with channel locks. If the motor is locked up the starter can't turn it. If all that doesnt work, then the starter could be bad.
Nate, I'm not sure what you mean when you say,"I can get it to whine but not turn over. The starter is trying to get it to turn, but I don't think it is getting any gas".
Separate and aprt from not getting any gas is the fact( if I understande you correctly) that the motor is not being cranked by the starter motor. You say "it whines". You are referring to the starter motor, right? the starter motor should not "whine". If this is what's happening by guess is the Bendix spring in the starter motor is broken. The bendix spring is a heavy spring that is mounter on s worm gear in the starter motor. When you go to start the motor by turning the key the starter motor turn and the spring travels down this worm gear and engages tthe geared flywheel and cranks the engine. As soon as the engine starts the flywheel is now turning the bendix spring faster that the starter motor and the spring kicks back to its original position. If the spring is broken it never engages the flywheel and the engine wont crank. The fact that you say the starter "whines" is what I would expect you to hear if the starter is at fault.
As far as no fuel flow there are 2 ifs: if you have an electric fuel pump, then there is a problem in the fuel flow. If you do not have a electric pump then the fuel pump runs off of the engines motion and since the engine is not cranking, the pump is not pumping and the fuel is not flowing.
Anything else you can add before we conclude that the starter has to come off?
