B&S 16HP Vanguard Starter Wont Engage
This is my first post and I would like to thank everyone in advance for the time and knowledge shared with me.
Now my issue is this, B&S Model 28Q777 Type 0623 A1 Code 9601044B lawn tractor wont start.
When I turn on the ignition switch the starter just spins. According to my Owners Guide there is a solenoid listed in the parts list for the elect. system. Would this serve the same purpose as the starter solenoid in a car? And if not, would changing the starter be advised for someone with no small engine mechanical experiance?
Once again, thank you AIO

The starter gear on this engine relies upon inertia to engage the engine and crank it over.
The starter solenoid is good if the starter is spinning. The battery may be weak and if not delivering sufficient current to the starter, it can just spin and not engage. The starter gear on starter drive may also be stuck and not moving into the engaged position.
I would have the battery load tested and make sure all the connections are clean and tight. Next I would check the starter gear to see if it's loose and can move up the drive and engage the flywheel. The starter drive can be replaced without having to replace the entire starter.

Well after tearing the engine cowling off,I pulled the top of the engine cover off so I could get to the 2 screws that cover the Bendix gear and was able to see that 2 teeth have sheared off the fly wheel. I turned the top of the engine back then tried to start the engine, but when it got to the missing teeth in the flywheel the engine locked and the Bendix just spins.
Is there anything that you can think of that I should be aware off before I try to remove the flywheel?
TIA
BTW; The engine didn't lock as in unable to move the crank.

Be careful when removing the flywheel, there is an alternator coil winding mounted to the engine block underneath the flywheel. If you pry up on the flywheel take care not to damage the alternator. I would suggest using a Briggs flywheel puller or equiv. to get the flywheel off.

Thank you, at this point I've decided that the possible damage I could cause by far outways the cost of having a pro get my tractor running. So it's off to the shop I go.
Once again, thanks AIO
