About 4 months ago I started working on my first bike, I kept having trouble with aligning the damn chain and sprocket and then my bike got rained on so the magneto and electric coil is more than likely shot. It’s been 4 months and I just dug it out of the garage to try and fix it cuz I don’t wanna waste 100 bucks. Is it possible that the system has dried out and is functional, or should I buy new parts, and does anyone have any tips to align the freaking sprocket so the chain doesn’t pop off every time i try to get it going. I’m asking because I don’t want to waste any time if this thing ends up being a total loss
