Technician: Wayne, Engine Rebuilder replied 1 year ago

From what I have read from previous statements, it will start when sprayed with fluid, but dies when PTO is engaged. Does it run smoothly when just idling? From the sounds of it, the valves are out of adjustment. What engine is on this machine?

Hi, my name is***** will be assisting you.

Does the carburetor have a fuel shutoff solenoid on the bottom of it? If so we need to make certain that there is voltage getting to this solenoid at all times when the ignition key is turned to the on or run position. Also you can remove the fuel solenoid from the bottom of the carburetor and check to make certain that it is working properly. It sounds like you are running out of fuel which is causing the engine to die, especially since you can get it restarted by spraying with starting fluid.

Does it die as soon as you try to engage the blades? Or do the blades come on and start to run or turn and then the engine die?

Ask Your Own Small Engine Question
Customer reply replied 1 year ago
Blades do engage but everything shuts down pretty much immediately
Technician: JohnF2015, Technician replied 1 year ago

What happens if you keep the choke on while engaging the blades? Will the engine continue to run?

Ask Your Own Small Engine Question
Customer reply replied 1 year ago
Haven't been able to start i past the initial blast of fluid pulled the fuel solenoid from bottom of carb still attached to electrical, plugged carb hole with another bolt and cranked right over dies the minute I disengage parking brake
Customer reply replied 1 year ago
Blades will not engage either
Technician: JohnF2015, Technician replied 1 year ago

So as long as you leave the parking brake engaged or don't try to engage the mower deck the engine will run fine?

This sounds like a seat safety switch issue to me. The seat safety switch is not recognizing that you are present in the seat therefore it tells the rest of the system to kill the engine if the parking brake is released or the mower deck is engaged.

Ask Your Own Small Engine Question
Customer reply replied 1 year ago
Will I bypass safety switch by unplugging and daisy chaining the connection with a wire?
Technician: JohnF2015, Technician replied 1 year ago

How many wires are coming into the seat switch?

Ask Your Own Small Engine Question
Customer reply replied 1 year ago
2 one black one white
Technician: JohnF2015, Technician replied 1 year ago

If your switch itself is gray then you will want to jumper these two wires.

If your switch itself is black then just unplug the connector and leave it with no jumper.

Try and see if the machine will continue to run then.

Ask Your Own Small Engine Question
Customer reply replied 1 year ago
It does as long as the brake is engaged
Technician: JohnF2015, Technician replied 1 year ago

Even with the seat switch unplugged and bypassed?

Then it has to be a relay in the system that is causing the problem. Depending on the serial number of the machine the relay could be in one of two places. One is in the fuse block with the other fuses on the newer machines and the older machines has a relay on a separate connector from the other fuses.

I am including two diagrams of the wiring that may help you locate your relay.

The first diagram is of the older systems and the second is the newer system.

Ask Your Own Small Engine Question
Technician: JohnF2015, Technician replied 1 year ago

Sorry those diagrams loaded in the reverse positions.

The first one is the newer system, the second one is the older system.

Ask Your Own Small Engine Question
Customer reply replied 1 year ago
Yeah I don't know what that means
Technician: JohnF2015, Technician replied 1 year ago

There is a serial number break where the wiring changed therefore depending on how old your machine is it will have one or the other of the wiring systems on it. You haven't provided the serial number of the machine for me so I don't know which one you actually have. Both have a relay which sounds like is the problem since we have tried everything else at this point.

Thank you it has been a pleasure to assist you.

Please take a moment to rate your experience.

I'm looking for a inline fuse ?
Technician: JohnF2015, Technician replied 1 year ago

No, not an inline fuse.

It will be a black box about one inch square that you are looking for. It is a relay that works similar to a fuse.

far I have replaced the plug, the fuel pump, the relay, and the PTO switch its seems as though I'm not getting fuel so in order to start the machine I have to pull the fuel solenoid and plug carb other another bolt, which does allow me to start the mower and it does run however I release the parking break it kills, I engage the control arms it kills and I engage PTO ( which was the only issue in the beginning ) it kills kind of tells me all of my safety switches are working and I bypassed the seat switch as well all of my fuses have been replaced and I have done a pretty thorough inspection of my wires and I don't see any breaks, cuts or places where there have been any arcs . Any ideas ????
Technician: JohnF2015, Technician replied 1 year ago

Based on the information that you have provided to me. The engine runs good until you either release the parking brake or engage the drive control arms. This tells me that you have a seat safety switch problem that is not recognizing that you are in the seat, it then tells the rest of the system to shut down when you either release the brake or move one of the drive levers from the neutral position.

It has to either be the seat safety switch or a relay going to that seat switch.

Ask Your Own Small Engine Question
Customer reply replied 1 year ago
The only way I can start the machine is by pulling the fuel solenoid , it runs but will not allow me to disengage the parking brake without killing, will not allow PTO to engage without killing and if I move control arms from neutral position it kills. As I've stated earlier I've replaced fuel pump. Filter, plug, #24 relay, PTO switch and now the seat switch still does not start in regular manner and does not operate. Any thoughts on valve adjustment? Will this miraculously rectify the initial PTO and subsequent brake and control arm issues
Technician: JohnF2015, Technician replied 1 year ago

Since it is killing the engine as soon as you move the control arms from neutral, disengage the parking brake or engage the PTO switch it has to be a seat safety switch issue. Either the switch itself or in the wiring coming up to the switch.

Valve adjustments will not correct that issue.

It also sounds like you may have a problem with the fuel solenoid or voltage coming to it, if you have to pull the solenoid in order to get the engine to run. Completely unrelated to the other issue of killing the engine when the controls are moved, brake disengaged or PTO engaged.

Are you completely removing the fuel solenoid from the carburetor in order to get it to run? If so, I would check voltage coming to the solenoid, if you are getting a constant steady 12 + volts then I would thoroughly clean the solenoid plunger. I have seen these stick or hang at times and not open up as it should which will keep the engine from starting and running.

How about the ignition switch as a possibility?
Technician: JohnF2015, Technician replied 1 year ago

Not likely.

Based on the symptoms and what you have described as the issue it has to be either the seat safety switch or a relay that is in the safety wiring that is causing your problem.

If you are not getting voltage to the fuel solenoid then I might suspect a switch problem but you haven't mentioned anything about that up to this comment. I did suggest that you check voltage coming to the fuel solenoid in my last comment.

Ask Your Own Small Engine Question
Customer reply replied 1 year ago
Had no voltage to fuel solenoid replaced every switch in between that and the ignition switch $80 later I spent anothe $15 on the ignition switch and it fired right up all systems working now
Technician: JohnF2015, Technician replied 1 year ago

With no voltage to the fuel solenoid then I would have suggested wiring or the ignition switch. The ignition switch however normally would have nothing to do with the engine stalling or dying when you release the parking brake or engage the mower deck. I think this one was a combination of issues.

I am glad that you were able to solve the issue.
