Kohler magnum 321 rebuild

Recommended Posts

Ok, I have dived right in to ATV motors before... nothing for the bottom end.. that scares me!! My 14hp smokes, regularly... is it worth a rebuild.... this is gonna be used for snow blowing. The 14hp is new to me, the end of this winter. Also, is it no points? The spark plug wire runs right inside the engine shroud....

How much smoking are we talking about, that looks like it's got plenty of life left.

Magnum use a magneto no points.  Pill the head see if piston is marked.  If STd or .010 or even ,020 overhaul it.

An overhaul done correctly will not be cheap. Being in Maine and this tractor is for snow removal I would want maximum reliability. This includes boring,valve guides new valves and possibly a crank machining job.

Member @prondzy did a great tutorial on Kohler rebuilds, read it over and you will have some idea what needs to be done. Before you begin it would be a good idea to locate an engine shop with a good reputation and speak with them.

When you consider the durability and reliability of a Kohler engine the rebuild will be a good investment.

This service manual should be helpful too.

Don’t be scared. Don’t be afraid to ask questions either on the forum or by PM. 
Find yourself a good machine shop, with guys that don’t get their nails done or go to hair salons for haircuts. 

As stated, Member @prondzy did a great tutorial on Kohler rebuilds. The Kohler manual is a very good reference. 

I’ve seen YouTube videos on rebuilds and I would stay away from that site. In the videos I’ve seen, several important steps are left out or they just don’t know any better. These engines have their nuances and the manual is a excellent guide.  
The people that do the videos are like old ladies that leave an ingredient out of a recipe.
