I have been told there is a tab on the camshaft that breaks, requiring a total teardown. Is there a way to bypass this with a manual compression release ?

you could drill the head, tap the hole, and install a brass 1/4 turn petcock

I recommend fixing it right

 

I have a pull start Gravely L that has the homemade compression release mentioned above. I bought it that way.

Its an older 12 horse K engine.In a 65 105 but obviously out of a 125 or something with the 12 horse. I bought it rebuilt by I dont know who. It ran and started fine for a while, 3months, and now it wont turnover on compression. I took the side cover off and the spring is not broken but rather , just off. I have been told there is a tab broken on the end of the camshaft.

I hate to have to tear it completely down and rebuild on a fresh rebuild over this. Its the last part if it is on the cam. A ported head would get me thru til another rebuild. Whats the disadvantages. The head can be replaced later easily.

Dont know about the 301 number. Its an old cast Iron K engine , is what Im told. I could look at the numbers on it again if need be but I thought they were pretty common the same in cast iron kohler back in the cub days. The mower is a 65

The 12 HP Kohler is a model K-301, that's what CAT was trying to tell you.

If it were my engine, I would tear it down to make sure nothing else is messed up. If a piece of the Compression release broke off, it can get into the gear train and really cause some damage to the whole engine.

Most definitely get in there and fix it correctly.

If it's broke that piece can cause big problems internally.

I agree. Those engines are a real workhorse and will last for a long time if properly rebuilt. They are well worth the time to pull it apart and do the repair. Get yourself a copy of the Kohler K series service manual from the Kohler site and have a look at the procedures for tearing the engine down and fixing this problem. That will let you know what you are up against. Hopefully nothing else is damaged and you are mostly looking at the labour to do the job.

Your not the only one, computers are an animal of there own.

Yes, thoses K-series last, would take the time to do it right, quick fixes can lead to more problems.

 I took the side cover off and the spring is not broken but rather , just off.

So it came unhooked? If it did, it might just be a simple matter of rehooking the spring on the flyweight.

 

Edit: Unless somebody's been in the engine already, bending the tab around and making it weaker, it would take a lot to snap it off.

I was told they bend the tabs after they are worn and then they break.  If the spring is off, there's a reason....? Do the spring ends just hook over the steel plate at where they reach. I cant tell where they should hook.  I'd hook them up and try it.
