changed plugs wires and rotor... tried starting and nothing m,,, looked at carb to see if fuel is squirting and it is ..really good stream.. when pulled plugs i removed coil wire and cranked engine and fuel sprayed out of the left half of the engine.. what up ? flooded?? i cant even get this boat started now.. getin pisd off<br />see other post... Uh oh whats wrong for other detail... oh i also put in some water absorber in the fuel.. but only have a 1/4 tank so/// dont know if it will do any good... guess ill have to pay the boat "so called mechanic" at the marina to look at it?? since its in the well of a marina where i have freinds who used to work there and they wont or cant come up to work on it at this spot ..dont ask why .. guess some sort of fued? oh well ... All i want is to get it out of the water!!!! and its not happening

Do you mean it sprayed out of the spark plug holes?<br /><br />Why start a new thread on the same topic, makes it difficult to follow.<br /><br />Aldo

Re: see uh oh.?? now engine wont start???

Ok,if I am following this correctly when you pulled the plugs "fuel shot out" of the spark plug holes ? If you are sure it is fuel and not water, I would have to say the float(or needle) is sticking on the carb allowing gas to overflow the float bowl. Pretty simple to check.Open throttle wide, Crank over engine to build up fuel presure, look down throat of carb with flashlight, you should NOT see fuel running into the intake manifold.

Re: see uh oh.?? now engine wont start???

Wow, it just keeps getting better and better for you huh? <br />OK, step by step here.<br />You did a good tune up, plugs coil, ignition etc. ran fine with just a little misfire or backfire once in a while. <br />Parked it for 2 weeks, hard starting then ran good for a little bit. Shut it off, started it and it was backfiring at high RPM's. <br />Tried it later after looking things over, wouldn't stay running. Now it won't start at all.<br /><br />First thing, do you have spark at the plugs? A coil will do this, then crap out completely.If you have spark, look to the timing. You said you adjusted this with the tune up. Unless your chain or gears are worn, you shouldn't have trouble with this. <br />You removed plugs and fuel sprayed from the side of the engine, I assume the spark plug holes. If it sprayed from the block, there is no helping this one. So you have flooded to the point of filling the cylinders. Someone asked if this was all fuel or water. The fuel should burn if you have spark unless you are dumping way way too much in. If you do have spark at the plugs....read on.<br />Move to the carb. The fuel you see runing in, is this when you pump the throttle? If it is, this has nothing to do with your problem. This is coming from the accelerator pump. Carbs have 3 circuits if you want to call them that. The idle which is a low flow adjusted by the set screws on the base of the carb. The higher flow circuit is measured by metering rods and float level. Then the acceleration, gives it a short burst of fuel to make up for the instant of lean condition when you open the throttle fast. To get that much fuel in the cylinders either the fuel is water saturated to the point it won't burn, or you are dumping too much in. I would vote for the second choice, that much water would lock the engine or hydrolic the engine and would leak down into the oil eventually. <br />This brings us back to the carb. <br />Possibilities, either the float has a small hole developed in it which is normal wear. Fuel enters the float itself making it heavy so it won't float. It drops in the float bowl allowing a constant flow of gas into the bowl from the fuel pump. This is dumping into the engine flooding it very bad. or you have a dirty or dry float needle valve. The float lifts the needle valve into place against the seat closing off the fuel supply when the correct level is reached. if this is dry cracked or dirty it will allow a lot of fuel to leak past flooding the engine. <br />One test to try, take the fuel line off of the carb and turn the engine a little while holding the fuel line in a glass jar. Get a few cups of gas in the jar, then leave it sit for 5 to 10 minutes. ifd you have that much water in it you will see it separating from the fuel, water will sink. Or you migh see beads of water on the sides of the jar. Water will beed, form drops and flow on a surface different than gas. Be extremely careful doing this, disconnect the distributor wire at the distributor first to avoid any spark. Don't want to go poof!<br />If you have a book and know about carbs take the carb apart and put a kit in it. By the way, what kind of carb is it? If i happens to be a Holley the float is easy to check and set without taking anything apart. I wouldn't recomend taking a holley apart without a little know how. if it is a Rochester, they are very simple, go ahead and dig in. Just remember exactly where things go. Put a kit in it, check the float level. Then when you are sure the float is set right, check it again. Then just before you put it back together, check the float again just to make sure you did it right the second time. <br />I still think your problem is in the carb. It sounds like your running lean, but if it shot fuel out, definately flooded beyond any hope of starting.<br />Let me know if you have spark at the plugs.

I think that alter-native, burned or sank his boat...oh well, at least he doesen't have that bunch of problems anymore. <br />Kinda reminds me of my 19 year old son. Problems, (w/his truck), problems, problems. And all that it is, is a loose nut behind the wheel! <br /><br />ALTERNATIVE, get a grip on yourself! and read and learn. If you can't run with the big dogs, stay on , (or under), the porch...sl

Re: see uh oh.?? now engine wont start???

I think he is letting this problem overwhelm him. I still think it is a minor carb problem by all explinations on all of the different threads. <br />To ALternative, don't take every sympton as a new problem, it is most likely all related. As is typical with most mechanical problems it is getting worse. Slow down, relax, read everyones suggestions. <br />Also let me know what carb you have, I am still stuck on that idea as the first place to look.<br />Don't get discouraged, relax and go slow thinkin about how everything works together.

Re: see uh oh.?? now engine wont start???

thanks deputy... its not a holley.Rochester carb it is a two barrel.. i did check spark at plug and its sparkin...and yes the fuel came from spark plug holes.. too flooded?<br />I also think the carb is bad.. probably need to rebuild. But could the carb be all related to previous problems.. from start? (hard starting, backfire, rough running- Choke stuck open?) or could it not be hot enough spark.? will have marina mechanic try to diagnose today...? hope i can at least get running to get to the launch....thanks again Deputuy

Re: see uh oh.?? now engine wont start???

Not a porblem. <br />Yes the carb could definately be the cause of all of the problems. <br />Good news, the rochester 2bbl is one of the easiest carbs to work on, very few parts. At Napa a carb kit will run between 20 and 30. You will need the number off of the side of the carb to get the kit. If you go to a marine dealer you may need the number off of an aluminum tab on the top of the carb.<br />Rochester 2jets are good and very simple carbs like I said, but they have a bad habit of having float trouble. The guys at the race track where I run use a lot of these Rochester 2bbls on the cruiser class. They work great, then all of a sudden they start popping and flooding.<br />If you have spark at the plugs and the timing is off, from what you have described the carb is the next step, it about has to be the carb.<br />It could of course be internal with the engine, but the synptoms you describe don't fit.<br />To rebuild the carb you will need a 1/2 inch wrench to get the carb off, a philips scredriver and a flat screwdriver, and that's about it. Also have handy a few toothpicks to clean the passages with, do not use wire or anything abrasive, and have a can of Gumout carb cleaner. Don't be afraid to use the whole can, things in there need to be completely dirt free, even a speck will make it run poor.<br />There should be an instruction sheet with the carb kit that will guide you step by step.<br />The only parts that could fall out and get lost is a small BB in the power valve. Work over a white rag in case you lose this. The kit should have a new one with it.<br />Good luck and as always let me know.

Re: see uh oh.?? now engine wont start???

Since he did a tune up, and did not touch the carb, lets look at the tune up components.. Sounds like a cracked distributor cap or contamination, like grease on the cap, or coil wire... or the top of the coil. If this is breaker point ignition, then the points could be closed up and not doing their job.... this seems to go along with it working breifly and then skipping and popping and now not working at all... The gas in the cyl. is most likely just flooding.

Re: see uh oh.?? now engine wont start???

Sorry for the two replys in a row... Just becasue you know you just changed the ignition components, dont assume that that could not be the problem. The back fireing under load is quite indicative of ignition cross fire.. Meaning that the ignition spark jumps across the wires, or across the top of the distributor cap, or from the center coil connection to the plug connection all out of time because it is not following the connection that the rotor is intended to create as the distributor turns..<br /><br />Check the path the wires are taking, loosen them from all their gromets, wipe the wires clean of and grease from dirty hands..., and remove each plug, clean/wipe it off then remove the wire from the dist. cap and clean the boot and the terminal for each cylender one at a time (which reminds me to ask if you are sure that the fire order is perfect, or is one wire out of sequence... ) replace everything and retry. While the plugs are out crank the engine with the coil wire removed for 10-15 seconds w/o any throttle to clear out any fuel remaining in the cylinders....<br /><br />Good luck.

Re: see uh oh.?? now engine wont start???

Paul, have you checked all of the other threads started on this? It sounds like it ran a few months after the tuneup. he also said he added electronic ignotion, AND points??<br />I suggested tghe coil could also be bad and recommended he put the old cap and stuff back on one at a time.<br />It is the large volume of gas build up that makes me wonder about carb. <br />If you haven't read them, check his other threads. It could still be many things!<br />He just needs to take time to go through everything step by step. I think he was overwhelmed and thought he had several new problems popping up.

What did the distributor cap look like? If it is a rochester 2jet they are easy to work on. NAPA has kits at decent prices, from 20 to 30 bucks.
