Re: please help.. locking screw is stuck..
I'm sure we're all pretty sure that you don't have a clue about what you are
Anybody that would run a 2 stroke motor with no oil premixed in the gas and then bother to think that they will be adding performance parts to it afterwards
needs a lesson in thinking clearly. Especially 5 tanks of gas.
I'm not going to lecture you, but at the same time don't think you deserve help fixing something you more or less intentionally destroyed.
Good luck to you and I hope you don't work on your own car!
