Pulling my hair out

Currently trying to figure out my yz125 its a 1987 model with pvl ignition ive only had the bike for about 2 weeks... so hear is the problem lol.. it has no spark when you first crank it up for the day has to be pulled after that starts first kick and runs great 1st 2nd and 3rd hit 4th and up horrible bog after about 3/4 throttle...

Cleaned carb, tested stator, new coil plug and cap.. running caster 927 at 32:1 this thing has me completely stumped

Also the rotor is keyless when i called pvl they said set it .2mm btdc

FINALLY FIGURED IT OUT THE PVL IGNITION IS VERY FICKLE NON RESISTOR PLUG USING MASKING TAPE AS A SPACER TO SET EVERYTHING 1.4 MM BTDC
