hi i have just bought a cmp giles 202 40 size, used. but it didn't come with any manual

so i have a few questions if anyone can help me out.
where can i get a manual, that would be the best. the fuel tank, the guy that had it before me mounted it to the wing under teh cannopy. the only problem is that it is too far from the engine, not enought presure to keep the fuel flowing during vertical flight. the servo for the throttle was a prob but my friend helped me out by making a brase for the servo and mounting it just above teh front of the wing under the cannopy.
where is the c of g we are not sure where that is about, when were flying her she seems to be a bit tail heavy.
and the engine thrust line, should it be facing down a bit?
if anyone could hepl me with these few questions i would be most greatful
thankyou for you time
