Ranger,

It sounds like you might have a damaged inlet valve. bigshock

Did you check the valves when you had the head off? confused

Have you checked the carby as well i.e removed bowl and cleaned the jets (especially the one under the idle screw)? woot

Check this stuff first and let me know what you find. cheers2
