good jump

been trying to get my camaro to start after the long winder
i changed the oil and loosened the rockers a little to allow it to turn over easier
and advanced the timing a bit to allow it to light up easier
and after all that i cant get a good enough jump to get it to start
tried jumper cables, jumper pack, and a new battery
by the time i get it to prime it runs out of juice
im going to charge my battery for a while (no charger other than jumpers so its gonna be a pain
but any way im gonna jump the hell out of it (had 2 different chargers and both got broke by some employey
how you brake a knob duh if it goes 0 min to 60 min and hold i9f you spin it farther it stays on longer right
and the other was my personal that i let some one use and said this is mine not the companies so be carefulk ok dum ditty dum
needless to say i got it back and the knob to switch from 6 to 12 vcolts is somehow broke and the cord has a slice it like what the
then they return it screaming about what a peice of shit it was itsd like thank you very much @$$ hole then they say that i gave it to hi9mk broke
i was charging a battery when he asked to borrow it and unhooked it and said just hook it up and let it sit over night (trickle)
oh no i gave it to him broke grrrr any way now im stuck using jumpercabkles
anybody got anyhints to give many many repeted jumps in a short period of time????
probabkly noty too bad irt wasnt standard lol just pull me around the lot lol
