Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hi, my name is***** will be assisting you.
You can still use this with just a little bit of rewiring.
What color wires do you have on the engine connector?
What color wires are on the tractor connector?
Here's what I want you to do.
Do you have any wire butt connectors? If so we are going to need three in order to splice wires together.
I want you to cut the connector from the old engine leaving as much wire attached to the connector as you can.
Then we are going to cut and splice the old connector onto your new engine wiring and then you will be able to just plug it together with the tractor wiring and you will be ready to go mowing.
The old engine connector has what color wires on it?
Okay, Thank you for those pictures.
You will cut the black, gray, and red wires leaving a couple inches of wire on the connector.
You will cut the orange wire as close to the connector as you possibly can as it will not be used with the new set up.
You will then cut the connectors from the wires on the new engine as close to the back of the connectors as you can.
You will then connect the black to black, gray to gray and red to red on the new engine and the old connector.
Then you should be able to just plug the connector into the wiring on the tractor and you are ready to go mowing again.
Thank you it has been a pleasure to assist you.
Please take a moment to rate your experience.
It was for an extra AC charging wire but you don't have that on the new engine.
If you follow the instructions that I have provided you should have no issues.
Have a great week!!!
No, the black wire is a ground going back to the ignition coil from the connector. The gray wire is actually a power wire which supplies voltage to the fuel solenoid on the bottom of the carburetor in order to make it operate.
No the red wire is for your battery charging circuit which should pair up with the blue on the tractor harness connector. The only thing the orange may have been there for is headlights but since the wires are jumped in the tractor harness you should still have lights as well.
Was this a new engine that you installed or a used engine from another machine?
My first thought is that the carburetor is leaking fuel which would cause it to be flooded. Check your oil level in the crankcase as if this were the case you could get fuel into the oil or crankcase.
There is nothing in the wiring that would cause you to get a fuel smell when trying to start the engine.
Is the engine actually turning over or does it try to but never turn? Does it just come up on compression and stop?
What happens if you remove the spark plug and then try to crank the engine? Will it turn over then?
So the engine is not even turning over or cranking?
The fuel pump system doesn't matter, the fuel pump is vacuum operated not electric so there are no wires going to it that would make any difference.
The only reason that you would smell fuel is if the carburetor is overflowing and passing fuel through the float valve when the engine is not running therefore flooding the engine and when you try to start it you would smell the fuel.
I have been in the small engine/lawn equipment repair industry for 28 years and done many engine changes where I had to rewire in order to make engines work due to various different reasons. I assure you that we have the wires attached correctly, there has to be some other issue that is causing the fuel smell.
