Check the flywheel sheer pin. If the sheer pin is bent,but not completely cut it will throw the timing off and make it run poorly,as you describe-run into this problem on a cub cadet with 12 hp Kohler several years ago-like to never figured it out. Hope this helps.

Still sounds like a timing problem-running poor and back-fires alot. How are your valves? A burned
or warped valve might make it act like that. If I think of anything else I'll post it. If you solve your problem e-mail me the solution-you've got me curious. Good luck

Help anyone..... I have a kolher CV16S engine in a ford/new holland LS45H lawn tractor-- i don't know the year- runs great-but..... no power on any type of slope.. i mean no power. i can't seem to get the rpm's needed... even on the flats at full rpm, it sounds like i'm at about 3/4 speed. i've tried adjusting the cable but i still don't get the rpm that i need.. i know this engine is capable of more...also in reverse, it's dog slow... any help or suggestions would be greatly appreciated. thanks-chris

Perry,I've found Kohler k5 service manuals in downloadable pdf format at kohlerengines.com/servicemanuals-Read Mike's posting,he's got the timing marks,and just for me, check that flywheel key-I've been told it won't make any difference and maby it was a fluke or a coinsidence,but one old kohler seemed torun alot better once that bent key was corrected.And since I'm courious,once youget her runnin'let me know what did that fixed your problem, I'd like to know. Hope I came up with somthin' that helped-Bob

Perry, To be perfectly honest, most of my experience is with Briggs and Tecumseh. Worked on a few Kohlers in Vo-Tech (in cub cadet tractors)about 15 years ago. They're tough engines,but they can be real buggers. Don't recall the timing specs off the top of my head,but I'll try to see if I can find them for you. Hope I can come up with something useful. Best Wishes.

Timing mark is on the flywheel. Look through the 1/2 hole in the tin. There will be two marks indicated by a letter. I believe one is a T the other an S. T is top dead center where the points should just start to open. S is where the points gap should be checked to match the spec. I could have them swapped, since I do not have my book with me.

NO!

The points should just start to open at the "S" mark.

The best way to set the points (AND the timing) is to use a timing light with the engine running. The "S" mark should be visible centered in the timing hole cover in the blower housing, using the timing light.
