Just got "lightly" used E-8 ABA Orange Blossom Special, PSd-1. Question on smoke fluid: just one inlet for each engine, the larger of the two openings toward front/nose? Also, how do I know if I need to grease the worm gear (removing shell & truck)? Manual says 50 hrs. If I want to upgrade to PS-2, do I just order kit from MTH? Or better to have certified tech do it? Since there are two power units, does that make it more complicated and expensive?
