Question about Desa International 18hp Briggs And Stratton Vanguard Engine Vertical

Open Question

Vanguard 14 hp no spark

I can only get a spark when I unplug a 2 wire connector on the engine.
Then it will start.
It also runs the battery down, like the regulator or stator isnt working

23 hp engine will start great when cold, but after it run a short it will not start Brfiggs&Stratton vanguard V-Twin Vertical Ohv Engine start.


it sounds like a fuel starvation problem it is very possible theres a blocked vent in the carb. the carb will probably will need rebuilding not very difficult

I have a 14 hp vanguard that wont run because its not getting fuel,,I have replaced the lines,fuel filter and tonight replaced the pump,,all sugessted by grasshopper tech,,also replaced the tube going down...


The fuel pump works off vacuum pulses off the crankshaft. More than likely the carburetor needs to be removed and cleaned out. This is a common problem with some Briggs engines.

My 92 dakota is not getting any spark


Engine Fails To Start

The "Checking For Spark'' test should be performed prior to this test.

This is a basic test of the ignition system that systematically examines the battery, the coil, the engine controller, and its wiring harness and connections; the most likely culprits in a no-start condition at this stage.

Fabricate this special jumper with a 0.33 MF capacitor in-line to test the ignition coil

  1. Unplug the ignition coil harness connector at the coil.
  2. Connect a set of small jumper wires (18 gauge or smaller) between the disconnected harness terminals and the ignition coil terminals.

  1. Attach one lead of a a voltmeter to the positive (12V) jumper wire. Attach the negative side of the voltmeter to a good ground. Measure the voltage at the battery and confirm that enough current is available to operate the starting and ignition systems.
  2. Crank the engine for five seconds while monitoring the voltage at the coil positive terminal:
    1. If the voltage remains at zero, diagnosis of the fuel system should be performed. Also check the engine controller and auto shutdown relay.
    2. If voltage is at or near battery voltage and then drops to zero after one or two seconds of engine cranking, check the engine control module circuit.

WARNING

The ignition must be turned OFF prior to unplugging the engine controller connector. If it is not, electrical surging could occur causing damage to the unit or other electrical components in the vehicle.

  1. If the voltage remains at or near battery voltage during the entire five seconds, turn the ignition key OFF. Remove the 14-way connector on 1989 models, or the 60-way connector on 1990-96 models at the engine controller. Check the 14-way or 60-way connector for any spread terminals.
  1. Remove the test lead from the coil positive terminal. Connect an 18 gauge jumper wire between the battery positive terminal and the coil positive terminal.
  2. Make a special jumper cable (see illustration). Using the jumper MOMENTARILY ground terminal 12 on the 14-way connector (1989), or terminal 19 (see illustration) of the 1990-96 60-way connector. A spark should be generated at the coil wire when the ground is removed.
    1. If a spark is generated, replace the engine controller computer.
    2. If no spark is seen, use the special jumper to ground the coil negative terminal directly. If spark is produced, repair the wiring harness for an open circuit condition. If spark is not produced, replace the ignition coil
    this is for distributor ignition
THIS IS TESTING OF DISTRIBUTORLESS IGN
Testing

This procedure requires an ohmmeter to test the coil packs for primary and secondary resistance (specifications are given for an ambient temperature of 70-80°F/21-27°C).
88472320.gif

The two coil packs contain five independent coils, which fire paired cylinders (shown numbered)

  1. Disconnect the negative battery cable.
  2. Determine the manufacturer of the coil. It should be labeled either a Diamond or Toyodenso.

  1. Check the secondary resistance of each individual paired coil by connecting an ohmmeter across the coil towers. This must be done between the correct cylinder pairs: 3/2, 7/4, 1/6, 9/8, or 5/10. Resistance for a Diamond coil should be 11,300-15,300 ohms. For a Toyodenso manufactured coil pack, resistance should be 11,300-13,300 ohms.
88472323.gif

Use an ohmmeter to check secondary resistance as shown

  1. Check the primary resistance of the front coil pack by attaching an ohmmeter between the B+ coil terminal and either the right (cylinders 3/2), center (cylinder 7/4), or left coil (cylinders 1/6) terminals. Resistance for a Diamond coil should be 0.97-1.18 ohms. Resistance for a Toyodenso coil should be 0.95-1.20 ohms.
  2. To test the primary resistance of the rear coil pack, attach an ohmmeter between the B+ coil terminal (see illustration) and either the right (cylinders 9/8), or left (cylinders 5/10) coil terminals. Resistance for a Diamond coil should be 0.97-1.18 ohms. Resistance for a Toyodenso coil should be 0.95-1.20 ohms.
i hope this helps any more questions repl if help at all plz vote or comment me

Running a Vanguard 23 Hp on my Mud Motor.\r\nQ1: developing a hard starting problem, seems like starting on 1 cylinder, after the first tank of fuel this fall. Fuel filter, spark, and plug OK. Looking at...


It sounds like your valves are out of adjustment. Your starter will bog down if it is out of adjustment and stop at the compression release.
So just take your valve covers off and set your valve lash to
.006 intake
.008 exhaust

Engine won't stay running


check the fuses which are under the seat
Also it will not run unless the parking brake is set when your not setting on the seat

Have 303447 briggs 16 hp only fires one cylinder


Have you also changed the spark plug too. The ignition circuit is pretty simple, from the battery, the Coil is energized, the "points" or equivalent, through the "Distributor" or equivalent, and onto the Spark Plug. So it is a simple matter to work along the path, proving the "Integrity" at each, point by testing. IF it still doesn't fire after ensuring all Leads are OK, the Spark Plugs are proven OK, the Cables, the Points, & Distributor, . IT is either that or the Ignition Timing is OFF. Please check all those points.

Our Vanguard 14 hp was idling and stopped. It


If this engine has been sitting for awhile I would guess the carb. is gummed up and need a good cleaning. First thing I would do is try a fresh spark plug. Just because the plug looks good doesn't mean it is. If you have a fuel filter check this also. If it is getting fuel into the carb and has spark and compression I would remove the carb and clean it.

Hope this helps

I have a Woods Zero Turn Mow n Machine powered


Try taking the cover off to get to the fly wheel and use some fine sandpaper or emery cloth to clean off the magnets on the fly wheel and the two little prongs that set really close to the fly wheel.
My white wouldn't start right away and I did the above and now it starts great.

Let me know if that helps.

Thanks

Briggs 14 HP Vanguard runs well until PTO is engaged


First thing u might want to check is the governor--Make sure the spring and linkage is hooked up properly and the governor is moving freely.
