Need help with gravely 1642 starting

Mower acts like the battery is low charge and will not turn it over fast enough to start. It is a new battery. The engin will turn over but slow and almost stops at top compression. Then turns over slow some more. Have tried everything I can think of to fix. New battery, starter, cleaned all wires and connections.

What are your engine's model and spec numbers?

First thing I would do is adjust your valves.

whats the voltage on the battery? even though new to you, it could have set on a shelf for a while and need a trickle charge.

Lord knows that the Kohler Courage starters are absolute crap.

But you have been vague enough already...

But I won't jump through a bunch of hoops for some poster that wants to be vague, and give us as little info as possible...

What did you set the valves at, and how?

I am doing the best I can at this! Yes it is a new starter. I set the valves at .05 on intake and .06 on exhaust while at top dead center.

Then I would look at the ground cable where it bolts to the frame. Also, remove the spark plugs and crank, see if you get a bunch of fluid spraying out.

I have taken the ground off and cleaned it. It was bolted at the motor mount bolt. I also have removed the plug just to see if that would let the engine spin over easier with no bad motor noise and it did. I did not see any fuel spraying out then.

About the battery not being fully charged. I thought the same thing so I put it on charge over night and checked the voltage the next morning and it was like 13.6 volts.

Go back to your valve adjusting, do it right. Read the manual, and set the valves right first.

If you had done that, you would have set them to "specs", but you just loosely checked them....... The valve adjustment is critical because of the compression release, so go back and do it again.

Sorry, but with a brand new starter, and a brand new battery, well, let's try crossing the big terminals on the solenoid.
That will bypass almost everything.... If it still will not turn the engine over, then it is the valve adjust, or a bad compression release, hydrolocked engine, too much carbon. Unless one wants to consider a bad new starter, or whatever.....
But letting us know in advance what you have already done/tried would be polite....

I told you that I was doing the best that I can. I do not usually talk on these forums I just need some extra help because I've run out of ideas. I do not appreciate you being an ***!

So what about my last post????

You going to try and help us out a tad?

New starter, new battery, won't turn the engine over..........

Not many places to go from here!!!!

New battery, new starter, won't crank fully/fast....................

It narrows things down a bit..........

Try crossing the cables directly...... that would tell a lot..... If the valve adjust didn't work, then maybe the compression release is bad.... But you will have to get off of your butt and start testing these things.....

I just rechecked the valve adjustment after I got home from work. .004 on intake and .006 on exhaust and it still won't turn over very fast. What wires are you talking about crossing?

Putting a jumper cable directly on the positive terminal of the battery and starter... Then try it again with the negative jumper on the starter base and the other on the negative terminal. If your battery and starter are new, the starter should crank like it is new....

Ok I tried that and it spins over just the same. Still slow and almost stops at top compression.

you may want to test the starter. yeah, its new, but could still be faulty.

Ok I will check that but if that shows good I am taking it to the shop. I am out of stuff to try.

Ive had the ACR go out on a K series...may want to do a load test on the battery,i know you can still have 13v,but could fail as soon as you put a load on it,and double check all your double checks,slow down grab a cup of coffee and think about it,..

Yeah, if all that has been put up here is true, and I mean "true", then he may very well have a compression release problem,
but I am always skeptical, as I hate seeing anyone waste good money.

Do the same test with the plug out, the dang thing should crank screaming!!! If not, then you need to go back to the start, and
"start" over......
