I just bought a cub 1000 with a 10 HP kohler. I was looking for tricks and tips to get the most power out of that engine. What about plaining the head,bigger cam,carb just looking for ideas.

Valve job, cam,swap head to either a heart head or a LP head, bore .30 over new piston and rings  just clean and rebuild the carb

Kinda depends on what your rules say you can do

Are you building it into a puller? If so you'll need to upgrade your driveline and a few components of your rear end as well to handle it all. I know baerpath runs with a 10hp I believe and he can tell you how they run. In my honest opinion I wouldn't mess with a 10. Id go to a 14 or 16 if your going to go crazy with it but you might have around 7-8000$ in when your done.

Check your rules and see what you can do.    \     Check your rules and see what you can do.

 

Some like running a 18hp K361 cam for better lugging if your required to stay with OEM parts thats one I;d do. If you can run the same lift but longer duration check with Vogel's or another reputable cam grinder.   A stock engine that runs great won't do sqat if you can't get the hp to the track.  

Turn it into a puller 1st and get it to hook up then go for a better engine.   Clutch, rear end, tires, and weight system are just as if not more important  than a hot motor

K361 cams are getting very hard to come by and they usually sell for more than a Fully adjustable 2 piece Vogel cam.

 

Toss a fresh #30 carb on it and upgrade the ignition to either a solid state ignition or crank trigger and a LP head.Depending on the block you have it could be bored out and a 12hp piston could be used in it.Would have to see the casting numbers on the block though to confirm that it's either a 12hp block with 10hp bore or a standard 10hp block.

 

That's about all I would do with a 10/12hp block.

 

If you upgrade to a 14 0r 16hp block with a little work done to it you will have to put a good bit of money into the driveline to keep from blowing diffs,axles,driveshafts,clutches and gears apart every time you hook to the sled.

 

 

I used to Dead weight pull locally with a CC102 with a 12hp K301 block,It had an LP head,#30 carter,ring gear mini starter,shaved flywheel veins and a stock clutch with red spring.Did not have much money into it and pulled pretty good for a stock class tractor with an open Diff.

 

Go get a rule book from your local club and go over it and decide what class you want to run in then build your puller.
