Default Factory setting of Fuel mixture screw?

Does anyone know where the fuel mixture screw comes set from the factory? 2 turns out? 3 turns out? I really screwed up my carb cause the screw was too tight to break loose... and now I think maybe I didnt even need to turn it at all? Ive heard that they are about 3 turns out from the factory and that is what I was shooting for? I have a new carb on the way and trying to decide if it would be best to just leave it alone? I will be upsizing the jets to 145/150... Any help appreciated... Thanks

Default Re: Factory setting of Fuel mixture screw?

i beleive the stock fuel screw setting is about 2-2.5 turns out. but you need to turn it to where you think it will need to be, then run, check the plug, adjust, run, check plug, etc. until you have it dialed in.
