Two questions!

Ok, so q. No. 1- I have a Jinhao 82 with ef nib that feels really sketchy and I was wondering what I could do to slightly improve it. Going to a nibmeister is not really an option… q. No. 2- I write in English and Hebrew and was wondering if there is any difference nib for writing right to left? Dose it even matter that much? Thanks 🫶🏻🙏🏻
