I have a JcPenney rototiller. I need help with.

I have a JcPenney rototiller . I need help with. The model number is 3001A. It is 8 horsepower. I need to try to a recoil starter for it. I need to find an air filter for it. I need to find a carburetor for it. Thank you

Look at the engine. What kind of engine is it? There should be a a tag or stamped in one of the covers the model type and code numbers.

Google JC Penney rototiller. There is plenty of information there.

I have a girlfriend. What color is her hair?

C'mon Nick! You have to give us some useable info. People on this site are knowledgeable and helpful but they read that post and move on to someone they can actually help.
Bear with me and I'll try to help.
I can only assume by your post you have no experience with small engines. Not a problem, we all had to start somewhere. To me, learning something new is just about as fun as it gets.
Now J.C. Penney didn't build the engine. They bought whatever brand was the cheapest bid that year. If Tecumseh was cheaper in 1974, it could be Tecumseh powered. Maybe then in 1975 Briggs and Stratton was cheaper so that's what was used. J.C. Penney was pretty good about using Briggs engines. Sears liked the Tecumseh's for some strange reason.
Like T.R.K. said above, we MUST know the engine info first. Most parts needed to get an engine running after sitting for a few years can be found at your local auto parts store.
Just a guess but I figure you have a Briggs engine with a Flo-Jet carburetor.
You say you need a recoil starter. Is the starter assembly missing? Does it just need a new rope? Is the rewind spring broken? Rope can be found at a local hardware store. First few times you rewind a recoil they can drive you crazy! After 40+ years I could rewind one in my sleep. They are actually fun to fix when you get good at it.
If the spring broken near one end where the notch is you can just grind a new notch in the spring and reuse it. Probably last another 30 years that way. In either case, you don't need a recoil. You only would need a few cents worth of rope or to grind that notch with no money spent.
The local auto parts store can also get you a new black rubber handle if you need one.
Air filter: Again, try your local auto parts store.
Carburetor: These can usually be taken apart and refreshed to operate as good as new. Old stale gasoline does horrible things to carbs, but they can be disassembled and cleaned. The auto parts store can get new gaskets, needle and seat, and floats. So long as you can get all the tiny passages open, the carb should be fixable.
If you were local to me [northern Missouri] I'd be glad to teach you how to make the repairs just as someone [my big brother] taught me.
Hearing an engine run again can be very satisfying, especially if it was grandpa's old tiller that's been passed down.
Chime in with some more info and the people here will be happy to help.
Best of Luck!!

I didn't see a name plate for the engine. I need the whole recoil starter, all there is , is a stub shaft that the recoil starter turn when you pull the rope. It was taken off roughly twenty years ago. This tiller was my grandfathers. Thank you

The JC Penney rototiller model 3001A should be an 8 HP Briggs & Stratton engine.

Try "Jacks Small Engines" They have just about everything and they also have a forum you can ask questions of.
