    obviously but not how I test things . at minimum it is best to simply disconnect the coil's ground wire which may be easier than fiddling with the point screw but that would leave the condenser connected which personally I prefer to be disconnected. imho ...all components should be...

    ETEC are great engines but you do know Evinrude went belly up. ? Future servicing may be a consideration for you depending on your skills or dealer proximity willing to maintain ETECS after getting dumped by Evinrude. whatever you do get a EMM fault dump. post it here for experts to...

    Fuel Problem

    Did you give a good shot of engine cleaner like Evinrude engine cleaner or Mercury Power tune ....some like seafoam some not ... run it at full rpm to circulate the mix then drop rpms to idle I know it is not as good a fix as a carb job but....it could be an easier fix.

    Fuel Problem

    vapor separators are usually found on fuel injection engine... unless I am wrong ..again your Johnson 175hp 1995 seems to be a carb engine... on the parts place anyway .. idle passages may be clogged yet HS jet could be fine experts will chime in if so.... a carb tune up may be...
