What did I buy?

[Keith Spriggs]

I picked this up at the Topeka contest. I know it is a Fox and I think it is a .36. Any other information would be appreciated. I cleaned it up and started it. It starts very good and seems to run fine. It was mounted on a board and the seller said it had only been run a very short time and never was on a plane. The condition indicates this is true.

Keith;

     Looks like a Fox .36 circa 1974 it differs from the 1972 in that the space between the top two cylinder fins is filled in. Catalog # 13600  AMEE page 102 #136. FWIW

  A good plain bearing sport engine.  Some of them vibrated pretty badly, but others did not.    Careful  (LONG) slow breakin is necessary.

I have a 29 that looks exactly like it.  A 29 will have the displacement stamped on a lug, and a very thin venturi insert.  Mine runs a nice 2 stroke with a 10-5 on a Flight Streak.  Had it out this afternoon and it was great.  Stunt engine - you have to be kidding.  Lots of fun.  If you don't want it, I would be interested.  Probably a mental deficiency, but I like those old things.

It seemed to be pretty vibration free on the test stand. I realize that a test stand clamped to a short 2x4 with two 6 inch Cee clamps and the 2x4 held in a 5 inch Columbian vise is not the same as being on the nose of a plane.
I didn't notice the 3 inch oak plank top work bench vibrating very much

Be careful. If you push this thing too hard, it has a tendency to throw cranks.

A Fox 36 sport.

That's it alright. I am going to feel real bad if it goes for $ 5.00. LOL

By the way thanks to all of you. I now have a better idea what I have. I did find an owners manual online. I bet you would never find a needle valve if you needed it.

Keith;

   Guess you didn't need all the info I gave you? A Fox .36 Sport was enough.  LOL See you guys later--------

Bill what is the Catalog # 13600 you are referring to? I am totally lost as usual.

[Bill Gruby]

 Keith;

   That is Fox's catalog number 13600 is the basic engine number. If you wanted to buy the Crankcase it would be part #13601. But even this isn't written in stone. Cylinder Head is # 13602 --- Cylinder& piston are # 13604, Then they change to foul you up? Wrist pin 13506.  The reason for the change in the second two numbers is simple the first parts are for a .36 the others are for either a .35 or .36. Marvin would know more about this than I. Now you are completely messed up.

Actually I did understand, Thanks G-man. I am thinking pretty clear this morning. If I could remember where I put my teeth I would eat some breakfast. My wife wont help me look because I called her by an ex wife's name. She gave me a dirty look so I called her by another name. Still the wrong wife. She is really PO'ed now.

Hey Keith you did make it home to Cherokee okay or did she drive?   Better take care of her, cause she seemed as enthusiastic as you at Topeka.  By the way take care of that Fox and it will give you lots of fun times.  Remember to have castor oil in the fuel.  DOC Holliday
