Thinking Fox 36x engine question

Post  getback Sun Jan 05, 2014 12:51 pm

got the fox36 have been told it was an x series off this broken plane , took it apart and soaked it for about 3 weeks in marvel mystery oil , got broken loose from the green  filth that had it stuck . What I was wanting to know dose it have a ring on the piston ?  I think that it must have  a sleeve in the cyl. because there is not enough play to get the piston out but have not tried to remove it extensively don't want to break some important stuff if I don't have to. And what plug dose this take ? Thanks for the help  Two Cents Fox 36x engine question 00210 before I got the engine out  Thumbs Up

It does not have a ring, it's a lapped baffle piston. The sleeve can come out, but it's position is critical so only do it if necessary.

If you do decide to remove the sleeve let me know and I can explain how it's done.

Edit: I was told by a reliable source to a use K&B 1L or Fox Standard glow plugs.

I should also add that the bearings should be checked for roughness prior to running. Sometimes castor hardens on a bearing surface and it may appear that the bearing is bad when it actually isn't. A couple short runs to heat up the engine and that will usually disappear. If it was me I would run it and check afterwards.

Fuel can be anywhere from 10-25% nitro, but I would stay around 10% or so as parts for the 36X are hard to find. Oil content should be at least 20%.

I recommend Powermaster GMA 10/22 as it's a darn good fuel and can be run in just about any vintage Fox.

Prop sizes from high pitch 8" props to 9-6 or 9-7.

This was what was recommended to me by Ken Cook. He uses these engines.
