Hi..I was thinking rubber of the belts cannot
add much resistance unless very very tensioned..
..and I'll be a little worried about belts less reliability
if I put some chemicals on belts (also if only some WD40),
but may be I'm wrong: surely, for rubber, oil is very bad
(a bit corrosive), grease is probably ok, WD40 I don't know..
..about valve timing, if you change the timing by +-1 tooth
probably engine can still turn free (for 8v you can have
2 teeth of error in one direction or 1 tooth in the other
direction and engine still turn free) but you will change the
effective compression value (not the geometrical compression ratio),
similar effect you will have with right timing but using different cams,
the effective compression value will change..so in theory
for every type of cams and timing you should tune a little
the geometrical compression ratio (or for every geometrical
compression ratio find the more efficient cams and timing)
to obtain the maximum from the engine without have it knocking..
..but I don't thing your motor have wrong cam timing,
probably is a combination of high geometrical compression ratio (12!!!),
particular valve timing that is enhancing the compression value,
(may be also race stronger valve coils?), big bore,
and as you say new and tight components..
..if you use commercial emergency cables to put an additional
battery on the starter, they are effective only if a little "professional",
(big section ones), the smaller cables have too much resistance,
they get hot during use and the additional battery doesn't add
very much to the effective voltage on the starter..
