    Ask Grok...

    Here is the file on my outdrive. Notice how specific my question was.

    Ask Grok...

    I didn't get out this weekend, as I have a bit of a cold, but I did ask Grok, Elon Musk's AI tool, about some questions I had about my Ford 302's performance standards. The more specific I got, the more exact the answers were with all of my up-graded components. I had some questions about If I...

    1976 Ford 302 carburator problems (was lower re-build)

    It had 12+ volts to the solenoids from the switch and the tilt motor was new two years ago, so going towards the tilt motor, I found a frayed wire grounding it out and all handled now. Just have to clean everything up, button up a few things and take it out next weekend.

    1976 Ford 302 carburator problems (was lower re-build)

    Well, it started right up, just had to adjust the timing and idle a bit and all is good... except when I went to raise the outdrive the tilt didn't function. It did it for a while when I reinstalled the outdrive but mysteriously started working again. I'll have to trouble shoot the electrical...

    1987 4.3L OMC Cobra thermostat part number

    The thermostat is not a mandatory component, as when it is cold, it stays closed to warm up the engine faster; and when gets warm it opens up, allows the engine to stay cool. Without the thermostat you will have unrestricted flow to cool the engine, and the only downside is that it will take...

    1988 OMC Cobra 3.0L

    Sounds like the starter gear is not engaging with the flywheel, but that does not account for the motor dying, which could be a lot of things. There are some really good guys on this forum who can steer you in the right direction.

    1976 Ford 302 carburator problems (was lower re-build)

    I got my engine back together today, from the intake manifold to the carburetor, the thermostat housing and hoses, the distributer and electrical, and roughly timed. I did not try to start it, as I wanted to give the RTV a day or two to dry. I have pictures, but this website usually says my...

    1976 Ford 302 carburator problems (was lower re-build)

    Some more data. I took the carb and intake manifold off and cleaned them up. I took the float section of the carb apart and it seemed fine. I blew into the fuel intake, and it seemed to shut off when I moved the float up to level. I couldn't blow though - maybe the bulb had more pressure than...

    1976 Ford 302 carburator problems (was lower re-build)

    I tried welding the old cast iron intake manifold, but it was too rusty, and I blew a hole through from the bottom oil to the water passage on top, which is where the real rust was. The weld was not sticking to the rusty iron, I could peel it right off. It is about an inch by a half inch wide...

    1976 Ford 302 carburator problems (was lower re-build)

    Okay, so here is some data. The vacuum test was poor, either 12 or 15 in/hg. My tester zeros out at 3 and it was reading 15, so it was probably 12. Either way it is low. Also, I found oil in the bilge and in tracing it down, it was leaking from the bottom of the front of the intake manifold and...

    1976 Ford 302 carburator problems (was lower re-build)

    Looks like I have to open up the carb - may be a crack, too.

    1976 Ford 302 carburator problems (was lower re-build)

    I haven't done the test yet. But on the second manifestation, where I pump the bulb on the fuel line, and like the fuel pump, it pumps gas to the carburator. Wouldn't you expect it would just fill up the reservior and the float would stop the flow and it would be hard to pump? But instead, it...

    1976 Ford 302 carburator problems (was lower re-build)

    Yes, it seemed futile to try any adjustments. I will do a vacuum test.

    1976 Ford 302 carburator problems (was lower re-build)

    My lower rebuild went well, and I installed it back on my boat and looks like it is functioning, but the engine is running terribly - it won't idle. I can just get it down to about 2000 rpm and it start to miss and it dies at about 1500 rpm. In taking off the spark arrestor, I see gas squirting...

    1976 lower re-build. (Was 302 pops...)

    I got it pretty much together, just have to put the upper unit together with the lower. It will be a few weeks until I can take it out for a sea trial.

    1982 302STHRCNC 3L

    Coils are very specific to the distributer. I have a 1976 Ford 302 and went with the Pentronix electronic distributer model D231800 and their Flamethrower 2 coil, which eliminated the need for the ballust resistor, and of course, gapping the points. I get great spark with iridium plugs. I am...

    1976 lower re-build. (Was 302 pops...)

    I got it out! It didn't exactly fall out - I heated it up to 250, then 300 degrees and stood it up so the bearing could fall out, but it didn't. So I took it out hot with gloves and beat it against concrete, until it finally started to come out and punched it out the rest of the way. There are...

    1976 lower re-build. (Was 302 pops...)

    I got the lower pretty much together including the exhaust housing and the exhaust rudder. The only thing I had a problem with was in putting the gearcase head on, I need to pull the bearing out to replace the seals, which are behind it, and I haven't found a way to get the bearing out. I looked...
