ACR-spring K301S ?

[LJUSNINGEN 26]

Hi!

 

Bought another Wheel Horse some time ago, and finally got around to take the engine apart, to check that everything is in order.

Previous owner said it had flames coming out of the muffler...

Found two things, first of all exhaust valve has to be exchanged.

 

But the second was more fun....the spring holding the fly weights for the automatic compression reduction was missing, and someone had put a cable tie (plastic strap) in the engine to keep the tab from lifting the exhaust valve! A cable tie!? And also, they had drilled a hole in the top, and put a manual compression release there.

 

Now, I don't know if one could find that spring somewhere.

Looks like you have to buy a complete camshaft to get it?

Anyone know if I could find the spring for the K301S?

 

I attach a photo of the "new" C-120 8-speed, proving that there are some work to be done...  

I have removed the fueltank special holder, and bought a fuel pump instead....

Also have removed the DC-generator driven by the PTO, and ordered new Voltage Regulator from eBay, hoping the stator works.

 

To be continued....

The booster seat is an interesting item. I doubt that the spring is available any more, but could be.

Some people just shouldn't be allowed to use tools!

A couple of years ago my jd dealer did a dealer search and got a new compression release spring for me for a 12hp 301.

If you can't find just the spring somewhere, you can always find used cams with decent springs on eBay.

Well, problem solved. Found a cam with a spring at in my neighbours garage!  

Also installed a new exhaust valve, new fuel pump, new points and condenser.

New gaskets, new oil, etc...

So, now the engine runs like a charm! Just listen...without muffler though, so be ready to turn down your sound.

Sounds great, but remember that that engine should not idle below 1100 RPM's. Doing so will cause lack of lubrication.
