The cost of reworking the Enya .10 engines to make them original and working again,
The Enya .10 engines needed:
1 -- crankcase at $20.00
1 -- back plate at $14.00
Gaskets at $4.50
And I purchased 2 throttle control (for R/C) for $23.00 each.
Ordered the Enya parts from Ken Enya along with two engine boxes ($4.00 each) and two Enya wrenches ($3.00 each)
Parts plus shipping totaled $128.53 from Enya.

I have currently one completed (remanufactured) as good as new.
Currently, working on the 2nd one to look as good as the 1st one that I completed.



Now for the "Sanwa" Cox engines.
These Sanwa/Cox engines came from Japan as were the Enya engines.

For the Sanwa/Cox engines, which by the way are .051 engines ( with the ring on the bottom of the piston)
I had to get:
2 - venturi body intakes (aluminum)
2 - 5x40 screws
1 - spinner
I purchased the above from Burnie (Cox International)
And I made 2 punched out screens for the venturi.
I posted earlier on how I made the screens for the venturi

I also removed the aluminum tubing on the modified muffler,
and I made my own modification to the muffler on my little lathe.

So, here is what the Sanwa/Cox engines looked like before:







Now here is the after:
I did have a R/C carburetor in my stash of parts bin and installed it on one of them.







Those are very interesting mufflers that Sanwa had made?
You can have them either behind the engine or on the side?
