I got a blaster with no stater in it came with a crappy adjustable ebay one, but I have nothing to go off for this new one now cause there wasn’t one to mark, can anyone tell me how to find the timing? Or a good starting point? The seal behind the stater is like a way over done chicken skin lol someone was running it way advanced I think, please help!!
