Ok so i just got done doing a compression test on the side where it sounds something might be off, i got one 140 two at 145 and last at 150. Also just put new autolite 25s in that side of the motor gapped at .054. I have yet to compression test the other side due to not having a helper to tell me the compression so ive had to set up my phone and video the tester since it loses the pressure too quick. I’ll test the other side when i can get help but for now am going to pop new plugs in.. as for the fuel filter, least of my worries as of yet.
