What am I doing wrong here!

Ok guys I have a sirio .30 that I can't get dialed in right does anyone know that factory settings for this mill. I think I have the HSN and LSN right but the idea screw is given me trouble. At frist when I hit the brakes it would shut off now when I let off the brakes it will take off I kinda gave up there for a week or two but it is time to fix this rig. This mill is in my savage s25. I think I might need to put a return spring on it I dono? What am I doing wrong and or how would I go about getting this straightend out where should I start. I am at the end of my rope here probably cause I am lost! Thank you for your time and any help I get!

A return spring is always a good idea. I'm not really familiar with the Savage, but I can't see that it would hurt.

Well, if you turn on your radio and receiver, can you slide the carb barrol in at all by hand? If you can, then your trims on the radio need adjusted until the slide has some pressure on it holding it shut. Then you can fire it up and adjust your idle. Adjusting your idle screw with incorrect linkage means your not really adjusting it, except for when you apply brakes.

Your throttle servo should move about 1mm via the trigger before the carb moves from mechanical idle. That 1mm servo movement resulting no throttle movement has a term... but the only one coming to mind is "dead band" and I don't think that's right. Regardless, it's a mechanical gap to allow for idle adjustments and any servo twitching when idling.
