Briggs 14 HP Vanguard runs well until PTO is engaged

14 HP 1993 Briggs Vanguard with 279 Hours just had it serviced runs well until PTO is engaged then AMP Light comes on and eventually motor dies. The tractor will start right back up engage PTO same results. It feels like a fuel delivery problem but without PTO tractor seems to run fine. Is there anyway to check if PTO bearing is going bad and drawing too much amps.

    Thank you for the response, When I had the tractor service I asked the technician to check Alternator output he stated it was with in specs. But the same guy told me the Amp light was coming on when the PTO was engage because of a bad battery. I will check the Alternator output. The exhaust burns clean even when it is about to die.

    Have you checked the magneto/alternator output? Sounds like when the engine is loaded the plug isn't producing enough spark.

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.

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.

Check the govenor spring to see that it is not stretched out or popped off...there should be a colored spring on the throttle plate where the throttle lever connects to...also, there are several holes in the plate where the spring attaches...these hole will set the sensitivity of the govenor...you may need to make it more sensitive to hold the engine speed high when engaging the blades

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

.008 exhaust

Engine appears to run normaly until PTO is egaged,then it backfires and quits. Engine is an 18 HP Vanguard twin, model 350777.


Check you float in the carb I had one a few years back and it was partualy plugged cleaned it out and everthing worked fine. Also is the PTO binding up or bearings going bad putting an excessive load on the motor.
