target has trouble resetting?
a target on my em pinball has trouble resetting completely. on resetting, the target resets to about halfway up but then drops back down instead of coming all the way up and staying there. it is having trouble re-setting all the way up to its correct up position.
the plunger looks like it has loads of grease on it so i was thinking of dis-assembling the unit and cleaning the plunger as a starting point. but before i do this i thought i'd ask for some advice for other possible problems to look out for before i begin dis-assembling it?
in order to repair the target so that it resets correctly, what are other possible problems should i be looking for as to why the target won't reset properly?
any ideas?
