Misfire in dt115

[Boreal]

I have a dt115 year 1996 non EFI with a problem: it apparently only works with two cylinders, but testing with the stevens cd77 he has normal 144V outlet in each cilindro.But connecting the timing ligth he only does it activate the second and fourth cilinder.No first and third light does not work, although he is with the spark plugs cylinder 1.2 and 3 burning. I emphasize that I am using the right plugs (NGK BR8HSC-10) and a problem with them can be discarded. The rest of the magnet was also tested with a multimeter, with everything normal. Outset congratulate the excellent forum and appreciate any help from friends
