There is a reason why thousands of pretty smart guys... called technicians.... go to schools year after year.....
The main reason is so that they don't make bonehead mistakes when working inside engines...
On some of the early Command Twin engine blocks...there was an issue with an air pocket forming in the area that feeds the #1 intake lifter..
There is an update kit that solves this problem.....

You will never learn anything ....until you admit that you don't know it all....

In my opinion rebuilt engines are a waist of money. You pay as much as $1100
For a rebuilt kohler 20hp. You can get that engine $1600. Bottom line that rebuilt will never last as long as new engine don't you agree with me.

In my opinion...you have never been inside the classroom that taught small engine repair..
The bottom line ........

No I don't agree with you...and neither do the over 200 customers I have built engines for..
My rebuilt engines last 2000 to 3000 hours...and have had many reach 4500 hours...
I have 1 customer that brings me every new mower he purchases...and has me disassemble the engine...carefully inspect and fine tune the internal engine parts...realign the crosshatches.for maximum compression and minimal ring wear...and then. Reassemble the engine..

If you knew how to properly rebuild an engine...you wouldn't have to spend $1100. Or whatever...
You could rebuild it for the price of the parts....

If you can rebuild an engine and make it last 4500 hours. You can teach the kohler mechanical engineers a thing or two

Except for they water cooled engine. ask here on lawnsite how many guys have had their kohlers reach 4500 hours.

This so called bone head bought a Kohler short block and having 35plus years building engines does have some what of an level headed educated back ground of refurbishing complete engines, along with the existing heads and a updated kit was installed for the lifters of which I searched past threads,thanks to Richard Martin for bringing the subject up from his past experience with the Kohler engine. There's plenty of oil finding it's way to the lifter feeding galleries,lifters just refuse to pump up. This engine was running flawlessly until I changed the filter and oil and replaced with factory filter and oil.

There is a great big world out there beyond the walls of this site..

You still dont get it...Getting 4500 hrs from a new or rebuilt engine has more to do with the guy operating and sevicing the engine...than the company that built it...

I doubt I could teach much to the engineers at Kohler...they are pretty sharp..
The only difference is... they are building a production engine...and I build a handbuilt engine...
There arent too many engineers working on the assembly line...

Confusing ability with experience usually ends up with a frustrated mechanic..

If you have more than 1 lifter (intake #1) making noise..its not a lifter problem..
Check your oil pressure..sounds like the welch plug or the pickup tube fell out of the oilpump..
If you have about 4 psi oil pressure..thats probably what happened..the pump will pump a good volume of oil...but you dont have enough oil pressure to pump oil into the hydralic lifters..
you should be able to remove the oil sender and install your oil pressure gauge there..

If for some reason the lifters are just plain bad...stranger things have happened...
You can use : MELLING JB817 lifters...accept no substitute..all the other automotive lifters I have tried were a waste of time...
