New to all this!
 

I have a 100 that has been sitting for about 2 years. As with all vehicles, "it ran when I removed the battery" and walked away. What is the best approach for getting it back running? Thanks

Welcome to OCC!

After 2 years ya got some work ahead of ya.
1. clean out entire fuel system
2. Make sure no critters got into your engine tins or wiring.
3. Check or change all the old oils and fluids.
4. get a fresh battery..

After that you can try and crank her over without doing any damage.

Let us know if ya hit any pitfalls. Here to help if needed.

Should I drain and clean out the fuel tank? What would you recommend for cleaning out the tank?

Yes. Absolutely. Also lines, carb etc. Especially if gas was left in it. Entire fuel system

What Coop said!

By the way, pictures are GREAT

Here's what I'm working with. I was thinking of selling but I guess I'll try to get it running.

Looks like a nice tractor. I bet it wont be much trouble to get going. Make sure your clutch is not stuck.

And your PTO to the deck...

Nice tractor. It looks real good!

I like to add a little oil to cylinder thru spark plugs hole if the engine has been sitting a long time.

Looks real good boulder.

Hey Allen it looks like you’re old dually! Always love the old diamond tread tires too!
