I have in my possession an L&J Fox. I have disassembled it and cleaned it and put it back together. A sweet engine! I think I can see the mods that he does but was wondering if I've seen all:

Hemi head with angled plug
Stuffer BP
ABC P/L
Partially blocked bypass.

Is it the stock crank with the small machining on the counter weight, or is it an after-market crank?

Anything I missed?

I hope this engine finds a better home than the ARF Nobler I found it in, but that's where it's going back to. An engine of this apparent quality deserves a nice stunter to call home.

Hi Bill,

Larry sent me a sheet several years ago with everything he does to his reworks.  As to what you mention, it is correct.  I don't remember him adding an ABC P/S but I guess you could have him add it with a price.  The crank he machines and adds "heavy" metal to balance it.  Otherwise he pretty much just "Blue Prints" the engine, including polishing the throat of the venturi.

The one he did for me, and the one I did with his instructions, are very smooth running for a Fox .35.  I believe more power is delivered to the prop since it is not doing as much "shaking".  He recommends 15% nitro for fuel.

Hi Bill-
I  will bring you Larry's Fox 35 tuning instruction sheeet Wednesday. It is old and doesn't mention a lot of stuff that was done to the engine you have. Some of that could have been done by the owner. Guess the best bet would be to talk to Larry if he shows up at VSC.
