Hi Speedracerntrixie
I don't understand how the idle stop screw could cause this problem but I would like to hear how it could . Please let me know when u get a chance.
Thanks Soinks
most guys just get rid of the idle stop screw. If you are using it to adjust your idle speed the servo is constantly pulling against it. Add in the vibration from the engine and the servo is being worked really hard. This will cause the servo IC to heat up and the servo end points will drift. Most of the time I have seen the use of the idle stop screw result in stripped servo gears. It could also be that the slight side to side play that all carbs have is preventing it from falling on the same spot each time. I would suggest 2 things at this point. First get rid of the idle stop screw and adjust idle via TX. This will also allow you to shut the engine down with the TX. Second, pull the carb and make sure the throttle butterfly screw is tight.
