engine clicking on acceleration.

Been doing this for a while, can't really figure out why its doing it. Only when the throttle is pressed past 30% it starts to click. I figure its a stuck lifter or something? Maybe one of you have experienced this?

check the valvetrain for tightness, sounds like you might have a loose rocker.

if it happens under hard throttle or lugging the motor it could be detonation. try better gas or check your plugs and timing if it's an older motor
