Customer Question
it seems like the battery...
I have a Kohler Command 17.5 which I have trouble starting, it seems like the battery goes flat, even with a new battery. I've had a mechanic out who couldn't find anything wrong after one an a half hours testing all the electrical system, the motor always turns over a lot before it starts with jumper leads from the car, the motor has 250 hours on the clock, and runs perfect once motor is going

I will need to ask you some troubleshooting questions as we go.

Technician: Donald, Small Engine Technician replied 2 years ago

Do you still have to use jumper cables, even when your battery was new?

Ask Your Own Small Engine Question
Technician: Donald, Small Engine Technician replied 2 years ago

You stated that your engine turns over a lot, before it starts up. Have you tried spraying a small burst of carburetor cleaner, or starting fluid, directly into your carburetor, to see if your engine will start up a little quicker?

We can continue from here. Thanks!

if the battery has been one charger the motor will start.
no i have not done anything in reguards to the caburetor
Technician: Donald, Small Engine Technician replied 2 years ago

Thank you for this information. I would like to confirm something. Are you saying that your engine will start right up, as long as your battery is fully charged?

Customer reply replied 2 years ago
It will still wind over a lot but will start
Technician: Donald, Small Engine Technician replied 2 years ago

Do you have any carburetor cleaner in a can, or starting fluid?

Ask Your Own Small Engine Question
Customer reply replied 2 years ago
no
Technician: Donald, Small Engine Technician replied 2 years ago

The reason I asked, is because I am wondering if your engine will start right up, if you sprayed your carburetor directly, or primed it with a small amount of gas?

Technician: Donald, Small Engine Technician replied 2 years ago

I would like for you to check something, when you have a chance.

Ask Your Own Small Engine Question
Technician: Donald, Small Engine Technician replied 2 years ago

I would like for you to remove your air filter cover, and your air filter. After you remove these parts, check to see if your choke is fully closing.

I cant under stand why the battery seems to go flat the motor runs for a hour each time its started.
it is I use full choke to start the motor each time as it could be a week or to between starts
Technician: Donald, Small Engine Technician replied 2 years ago

Even with full choke, is your engine still hard to start? Do your battery go flat, only when you are attempting to start your engine, or does it go flat while you are out mowing?

Ask Your Own Small Engine Question
Technician: Donald, Small Engine Technician replied 2 years ago

These are only troubleshooting questions ...

Customer reply replied 2 years ago
it goes flat while its standing it charges up while mowing and will start after mowing for a while but still turns over a lot i guess the caberutor needs a clean
Technician: Donald, Small Engine Technician replied 2 years ago

As far as your hard starting issues, your carburetor may need a really good cleaning, but I would double check your choke first. Although your choke lever is in full choke position, does not mean that the choke valve/butterfly on your carburetor is fully closed.

Technician: Donald, Small Engine Technician replied 2 years ago

As far as your battery failure is concerned, you may have a short causing your battery to drain, when you are not using your mower.

Ask Your Own Small Engine Question
Technician: Donald, Small Engine Technician replied 2 years ago

When you get an opportunity, purchase a can of carburetor cleaner. We can use it to help troubleshoot our problem.

that what i think but the machinic could not find a short,i guess that does not mean anything
Customer reply replied 2 years ago
I have to go now I will get back later to day
Technician: Donald, Small Engine Technician replied 2 years ago

Okay. Take care. We can continue after you return later.

Ask Your Own Small Engine Question
Customer reply replied 2 years ago
I have checked the carburetor and the choke closers right, but noticed there's three holes in the flap about 4 to 5 mils each hole which surprised the machanic checking it out, it must come that way from manufacturer. I also had the battery checked and found the crank amps was down to 70 instead of about 300.
we tuned the motor over and there was plenty of fuel coming through, with the new battery the motor started straight away, I will let it stand for a week to see if the battery is draining
