According to my manual all the 402s have the same throttle pickup specs. The throttle butterfly on the carb should just begin to open at 6 degrees before top dead center and max spark advance is 27 degrees before top dead center. When adjusting the slow needle the carb must be fully closed engine idle speed is dependent on spark advance not throttle opening.
Yeah, but you need to borrow a light and check it.
So you know, WOT timing has nothing to do with idle, or stalling when gently dropping her into gear.
Jeff
figures eh.. from what i experiencing what could it be? after you seen the check list i checked offMost perceived " carburetor problems " turn out to be something else.------------So more trouble shooting needs to be done.
