Can't get the port engine to fire

how about a weak and/or failing ignition coil?....a weak coil can provide a weak spark that may trigger a test light but the spark is too weak to run the engine giving a false indication the coil is OK....

Well, that sucks. Went to try to check the timing today. Found the marks, started turning the engine over. Gave it a few gooses with the throttle, and it felt like it wanted to start and then it vomited think chocolate milk from the oil breather hose on top of the port valve cover. I opened the valve cover cap, and the inside is covered in chocolate milk, and when I checked the dipstick, it was the same thing.

Blown head valve? Something happen when the water pump failed? Not sure, but looks like I am going to have to remove the valve covers, heads, and check the head gaskets. And that looks like i will have to take off the exhaust manifolds on either side to gain access to the heads. They look pretty heavy, and am hoping that i can just unbolt and let slide over to the side while working on the engine.

Anyone have this problem before and correct action to take? I have not started searching youtube, yet, but am about to begin, since that is where every problem can be solved. :)

Thanks

Ed

Sorry the video is upside down (dang iphone), but should not affect the info. :)
 
Started the rebuild today. Holy crap.

Think about all of the areas where sea water and oil could mix.

Do you have an oil cooler?
The intake manifod has sea water traveling through it too.
If those items check out, move on to the more complicated things.
Could be a bad head gasket, cracked or rotted cylinder head.

As a baseline, I would do a compression test before removing the cylinder heads.
 
I left the throttle linkage off, as seen in the video, and tried pumping the throttle several times. No matter how many times I pumped the throttle, it would not start. It sounded like it wanted to many times.

Do you actually see fuel being squirted into the carb from the accel pump?
 
forget the starting fluid, pour about 3 or 4 oz`s in here to prime the carb

 
It started to overheat a little, but caught it and lowered the idle to get the temp right. Later found out that it was a bad water pump, and has been replaced. The next morning, the engine started, but cut out at low idle, and will not restart. I have verified that there is spark at the

Did you check the oil level and condition prior to starting the motor?
 
here are some more photos of the rebuild. I have the heads and intake manifold off. They are being cleaned right now. The gunk has been sucked out of the engine for the most part, and 10-40W has been poured into the crankcase to keep the crankshaft bathed in oil, vice oil and water. It rained all day today, so no work on the engine. Tomorrow, I get the thermostat, gasket kit, oil filter, and then start working on getting it all buttoned back up.

more photos. tomorrow I put some diesel fuel into the crankcase with the oil, and then rotate the engine to get it to circulate and clean a bit, then suck that crap out, and then do it again. Ugh

Yes, at the time, the level was high, but black, not milky. I think it just did not have time to have changed color at the time.

Yes. The carb was not the problem, and worked properly. I guess the rebuild of the carb is an added benefit. :)
 
Take the cap off and make sure the rotor is turning when your rolling the engine over, could be a broken timing gear or chain if it isn't or you could of jumped timing. You are not getting spark if it won't start even with quick start. Could also be a broken dist. shaft gear pin.
 
First thing when using starting fluid only a short squirt in the carb will let you know if it will start DO NOT TRY TO RUN THE MOTOR WITH IT. The noise you hear looks like it is coming from the electric fuel pump(not suppose to sound like that it may click but thats it).You need to check the compression of the cylinders and turn it over to see if there is water in the cylinders, Pull all the plugs and then check compression. Line up the timing mark on the crank pulley and see if the distributor rotor is in the #1 position when #1 cylinder is at top dead center, also with cap off turn engine over and make sure it is turning to check for a broken timing chain or distributor gear. Sure sounds like an out of time engine(could of slipped timing).
 
Loyd,

It appears that he had water intrusion and is in the process of rebuilding the engine....post #28.
