2 83 atc 110s no spark, no compression

Have 2 atc 110s one no spark, the other low compression, bought them cheap, need help on finding a wiring schematic and a way to check valve timing, any help would be appreciated.

Have you tried swapping any elecltricals from the low compression one to see if you could get spark to the other one. Like the coil cdi modual????.

Yes that was the first thing i tried, also did a continuity check of all wires, the only thing i could find obvious was that the kill switch is not there but it looks to me as if it is a normaly open circuit, which is why i would like to find a wiring diagram, and as for the low compression engine my son and i took the top end and jug and piston off that engine and put the good parts off the no spark engine and now am looking to see if i have the timing right, still will not fire up.:doh:
