Hi Tyler, just looked through them all and I think a fuel injection service is in order for the weak acceleration and heavy fuel use that a car of this size and engine capacity just shouldn't do.
I might try my hand at testing the O2 sensor any way. Thanks for putting up those pictures. It saved me the trouble of looking them up myself

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
