I took apart my flywheel cover and noticed the whole front face of the flywheel is corroded and has a little rust. Will it be fine? do I need to sand it down? Or get a new one.My blaster isn’t running too well right now it sputters a little bit and when the rpms drop it will do a few little burst of higher rpms sometimes. It also takes longer to rev down like it’s hanging for a few sec. I have looked for air leaks but haven’t checked inside the transmission or flywheel area because that’s a bit of a pain lol. My leak tester isn’t very good so I can’t exactly tell if I have a leak by the tester. I just have to see the bubbles from the soapy water themselves. Idk if the flywheel could cause those problems or not, thanks. I would show u a pic but it’s not working. Ps it had good spark
