    New day New Problem--1988 GM 5.7/Cobra oil at the plug wells---

    I noticed after my break in oil change that I seemed to be using or leaking oil. When I changed the cap rotor and wires I saw what was to me an alarming amount of fresh oil in the bilge. I cleaned the bilge and started the engine running on muffs in its stall . With a good light and engine...

    I currently have my electric choke wired to the side of my coil . I have read somewhere that it is not correctly connected by doing this.

    I put a new 31 series battery in the boat a few months ago that I bought at Wally World and fully charged it now reads 11.27 volts. I used two different meters and both read the same.
