I'm reassembling the valves on a 14HP K321 Kohler engine. It has a valve rotator on each valve which I'm assuming is OK. Which way should the springs be oriented - close coils up or down, or does it make a difference?

I don't remember if there is a preference. Check the manual in our Manuals Section. I always have the manual on the bench so that I don't screw up. Good Luck, Rick

 

I like this manual  http://gardentractor...service-manual/

 

Don't forget to double torque the rod.

I also have that manual and it is a good one, I just didn't read it carefully enough. Under the valve installation section, it states in a small paragraph that K241, K301, K321, and K341 models should have valve springs installed "close coils to the top". The last guy to rebuild this engine had them reversed. There is also a note I found stating "Some models (mine, K321) use a valve rotator on both valves". Thanks for the comments.

 

I'm trying to fix a hard, hard-starting (if at all) problem. The valves don't look too bad, but I'm having them re-ground now that I have them out., The head, on the other hand, needs work. The head gasket is blown out at two bolt holes and at one, the head has been eaten away into the hole. I'm having that area welded and the head re-surfaced. Then a new gasket and hope for the best.

Been there, I just bought a new head that time. Since then, I hand file the heads and use a machinists straight edge to get them flat. I've done it on 4 cylinder car engines too. What are you doing about the grenade gears?  I'm almost tempted to see this guy  http://newlondon.cra...5019180726.html   but I've got too many engines already. Good Luck, Rick

Well, the old LGT145 is running again. Had the head repaired and surfaced,  installed a new head gasket, checked the valve clearances, and set the timing. Must have been losing compression with that blown gasket. Thanks for all the advice.

Glad you got it running. I haven't messed with the valve rotators. Head gaskets can cause some issues.
