Hi there, pauly46 here

from your model type ch730 25 hp 0040 it seems that
this model does not need or use a smart spark ignition module

please check that you dont have a kill wire from your coil groundin somewhere between kill tab on your coil and the ignition switch

then if you still have no spark replace the ignition module
that has no spark - your engine has been running one 1 cyl
as soon you pulled the h t lead off the firing cyl the engine died
that tells you no fire on other side

i am sure these units do not use any diodes fitted between l/h and r/h kill wire tabs leading back to ignition switch , i think these are mainly on briggs vee twin

here is web site for service manual

enter as guest on the site
go to command pro twin
go to service manual section
select SM-24-690-07 ( replaces tp-2450c) from the list
download a copy and print


cheers hope it helps

What to do? I have a craftsman GT 5000 with a 25 HP Kohler and it will run for about 10 minutes and then start cutting out and die. I have changed the fuel filter with no resolve. What should I look at...


Make sure the choke is coming off. Check the compression.Many times the head gasket may leak when the engine heats up. Also check for spark sometimes the magneto can heat up and quit after running a while. See if it will run if you prime with a little fuel, if so ,some of the Kohler engines this size have a fuel pump that could be failing. Check for vapor lock. It takes air and fuel properly mixed, spark and compression any of these missing the engine dies.

If the fuel is set too high and the choke is on it is easy to flood it. The solution is to open the choke and keep the throttle low for a few turns to air dry the spark plugs then back to choke to start it again

Kohler command 20 twin engine - no spark


If there's no spark, then either the spark plug has come into contact with gas, or the ignition coil is bad. Try either replacing the spark plugs, or removing the old ones and seeing if the tips are damp.

If replacing them doesn't work or the plugs are dry, then try replacing the ignition coil.

My Kohler Command 20 HP running fine, shut down, won't restart. How should I troubleshoot this problem?


check for fuel try starting fluid if it fires on that then you have spark if it does not then you have a spark problem and seeing the command engine has two coils check the safety switches on the mower side

Does my 2 cylinder kohler engine have a firing coil


Yes, some of them have covers that cover the coil. you may have to remove a cover or two. the best way is to locate the spark plug and then follow the spark plug wire back. most of these engines depending on the year will have the coil under the flywheel and they use a magnet to trigger and produce the spark. Again not sure the year but to remove the flywheel a puller is needed and you will have to remove cover, Most of these twin cylinder engines use two coils, one for each cylinder.
Here is a website that may be helpful in testing the coils. hope this is helpful. good day.http://www.ehow.com/how_7880826_test-coil-kohler-command.html

Kohler cv15 no spark at the plug.


If you disconnected the stop wire it is a coil ground wire and still cannot get a spark to the head at about 1/4 inch from the head the coil is bad. The only other thing could be a broken or loose magnet under the flywheel but that is very very rare.
