Briggs and Stratton Vanguard 23Hp starter issues

I have a Briggs and Stratton Vanguard 23 Hp less than 5 years old with less than 500 hours mounted on an old Simplicity 4041. I've had no problems other than the starter bendix seems to stay engaged. It is a new starter, with a new voltage regulator and a new solenoid. I thought maybe I wired it reversed, but such is not the case. Got a clue what is wrong? Thank you! Tim

Take the starter off and give the bendix a realy good clean up and then splash some oil on it,,,they get very dry and sticky at times,,,you can test the starter uasing some jump leads stand on it though, dont hold it in your hands as it will spin out of your grip
hook the black lead to the caseing and tuch the red lead on the starter battery stud,,,it should spin up and strow the bendix out as soon as you take the lead off the bendix should slid back in if it dont oil it till dose also check the starter relay it could be sticking on holding the starter in

    hi its miket756 again

    have a look at the flywheel ring gear it may be that this ring gear is grabing the starter bendix and jaming it in gear and not letting it slide out of gear when you let go of the key,,,also try the starter solenoid with a light buld to check it realy is switching the starter off and not sticking on,,,

The starter may need shims between the engine and starter to permit the relative gears to release. Compare the two starters, if you still have the old one, for shaft length and bendix construction. Hope this helps!

    The starter should hang below the flywheel ring gear, so that it shouldn't stay engaged due to gravity. Does the bendix couple gears through inertia or due to the mechanical action of the solenoid? Can you tell if the starter motor is running when engaged? Try taking the solenoid small terminal wiring off and just jumper the two heavy terminals to run the starter. Does the bendix now release? The point here is to isolate the problem to either electrical or mechanical. What was wrong with the old starter and did it exhibit the same bendix problem? Is it possible to reverse the solenoid position? Take the top cover off of the engine so that you can see what is happening. By hand, push the starter gear into the flywheel gear--it should disengage easily. If it doesn't, look at the condition of the flywheel ring gear--are the teeth chewed or burred? Does the starter seem to be too close to the flywheel? Hang in there!


  • drallim Jun 06, 2010

    Another thought, remove the starter electrical connection, then try the key--does the solenoid 'click' every time you go to start? If it clicks only once, then investigate the solenoid wiring as that would suggest a self-latching relay. Can the solenoid be reversed in it's position? Keep on trying!

  • drallim Jun 07, 2010

    Did some on-line research. The starter relay is not sensitive to position as I thought. There is just the solenoid coil with one side tied to ground and the other side to the ignition switch (which sends +12 volts when key turned to start. Remove the coil connection and check for 12 volts all the time--suspect a bad ignition switch. Hope this gets things running!

HI,
Just a suggestion. Are you sure the gear on the starter motor has the spring in it to push the gear away from the flywheel after you release the key. ??

How do you remove the starter on Briggs & stratton V-twin 23 hp


You may need to remove the engine top cover to get at it maybe not...It is attached at the top of your engine where the fly wheel and fan are located..it spins the flywheel..if your engine is vertical it will be vertical if horizontal likewise.it normally has only two mounting bolts and a small wire or two..just remember where the small ones go..pretty much a easy job make sure you disconnect the battery or you will get sparks at the starter...good luck

Anti-foul plug adapters might be a temporary solution (treats the symptom and not the cause).

I have a 7 year-old craftsman mower with a 22 HP Briggs engine that has the same issue. After about an hour, the mower acts as if it is starving for fuel and then stalls. Then after about 5 minutes of sitting, it will run for a little while longer.
If your engine is similar to mine, then its carb has a fuel shut off solenoid which shuts off fuel to the Main Jet when Voltage is removed to prevent backfiring when the key is shut off.
Unfortunately, this solenoid can also cause the carb to starve for fuel when not working properly. In my case, when I cleaned the solenoid and the solenoid's connections, the tractor had no problem after that.

Hope that helps,
Steve
