Hey Guys.

I need help please. My Wonjan 200GYB has developed a illness I am trying to diagnose. When I get up to about 7000rpm, the motor starts to splatter and misfire. A While ago I first noticed it but it was not nearly as seveare and very intermediate. I suspect a glitch with the Ignition module. I say this because when the splatering starts, the revcounter starts to wonder madly around 5000 - 6500rpm, even though I am at 7000 - 7200rpm. I worsens as I try to go higer and disapears when I get back below 6800rpm. I am quite sure that it is not fuel starvation as you can feel there are throttle power left and giving some choke makes no differance.

Advise please Lads ??

Kind regards
