Primer Bulb For Fs 90r
I replaced the primer bulb but in doing so, the screen beneath came off. I replaced it not sure which way it went. Now the machine doesn't run right. Basically, it is backwards. Choke off to start and choke on to idle and cut.I don't know if something came loose from the carb. I replaced the screen 2x turning it over in case I had it backward.the owner manual doesn't address the primer bulb at all. If I could see how the bulb and screen goes on it would help.any help would be great.
