Hello all...

I am having an issue with trying to get a Kohler 19 to start and was wondering if any of you out there can possibly point me in the right direction?

The battery is new and fully charged, and the carb was just cleaned and rebuilt.

Please see the video below to see my issue and note that the key was being held in the start position during the course of the video..

Could the starter be going?

Thanks in advance!

Starter is likely Fine... Your valves need adjusting.

Ahhhh! Thank you! I will look into that!

I agree with KennyV on the valve adjusting. I think there is a built-in compresion release involving the exhaust valve. If the clearence is too much, it doesn't hold that exhaust valve open as it should, creating too much compression for the stater to roll the engine over. gregjo1948

Thank you again.

Hopefully I will be able to get to it this weekend and let you know how it goes.

Anyone know what the gap should be (.003, .004, etc)?

Thanks again!

OK Folks...

Took the cover off, and the valve on the left was flopping around in the breeze.
Unfortunately, after adjusting it to specs (.005), and trying to start it...it is still trying to start the same way (no change).

Is there anything else I can look into?

Just to verify, TDC is when the 3 indented dots on the side of the crank is lined up with the starter, correct? This is where it was when I adjust the valve.

Thanks again!

Did you adjust both intake and exhaust valves? Be sure that the valves are completely closed when you set them. gregjo1948

Yes Sir. Both where adjusted to .005 when at TDC.

I'm quite sure, after watching the video, the valves need correct adjusting. I,m not sure on your Kohler but on some engines the in&ex vavles are momentarily open at the same time to relieve some compression so the engine will roll over easier.TDC may not be when to set the gap. That's why I said to be sure the valves were closed when adjusting. gregjo1948

Roger.

I will double check on that.

Thank you!

Yes, you need to make sure you adjust at the correct TDC, as the engine rotates, check the piston location with a pencil or wooden stick in the plug hole. As the piston comes to top on one pass, the one valve will be closing as the other one is just starting to open, as you come up to the other{correct} top dead center, both valves will be fully closed.
