782 won’t fire….
 

Plowed snow a few weeks ago. Parked it in heated shop. Tried to move it around shop and no start. Plenty fuel in tank, tried wiring around safety switch, have spark, can’t say it’s the best, but enough I think it should at least fire.

Any suggestions or tips are appreciated.

Thanks in advance!

First, welcome to OCC.......... :Welcome2:

It takes three things to fire up an engine. Spark, Fuel, and Compression.

YOU said you have spark, I assume the compression hasn't changed in a few weeks, thus it must be fuel. Take the Air Cleaner off and mist in some "starter fluid" and see if it will start up.

Thank you!

I have already tried as much with starting fluid with cleaner off.

That’s why I do puzzled. It ran perfect when I was plowing. Nothing abnormal. Shut down normal, etc…

How do the points look? And is the gap in spec?

If it won’t even cough on starting fluid, I would suspect ignition-related issues.

I agree.

Prolly water in the carb bowl. BTDT

Bet it is points/condenser related.

Me too. :beerchug:

thanks for everyone's comments and help. I have done a little more research. the tractor has a Kohler M18 in it. I believe it is the ignition module.

My next question, do I have to pull the motor to replace? i have a the gas tank out of they way, taken out several bolts, but appears to have more under the bottom side???

any feedback to this?

Thanks in advance

IF.....you have a M-18 instead of a KT-17, then YES, the Ignition Magneto Coil is under the shrouds, and those have to be removed.

thats what I found, but I am not sure they will come off w/o pulling motor. Am I missing something? appears there are bolts on the shrouds underneath??

May I suggest that you do some diagnosis before you start throwing parts at your project.
Did you disconnect the white magneto kill wire at the plug, coming out of the grommet where the plug wires come out of the fan shroud?
If not, do that to eliminate a wiring issue instead of a maybe it is a bad mag coil guess.
And yes you have to pull the motor to get the fan shroud off as well as cleaning all the debris from the cooling fins around the cylinders.
You will find the mag coil packed full of chit also.
Pulling the engine is not a bad job, might take an hour the first time, successive times maybe 30 minutes.
let us know what you find.

Have you downloaded the free M-18 service manual on our site?
it will help you much.
