Carb getting fuel, not getting to motor

[Westside_JAX]

I've got an 15 HP '89 Evinrude E15ECEC. Motor was running fine for a couple of weeks after I replaced some missing parts that on my carb. Retainer was missing off of SS needle and carb cover was cracked. Like I said it was running smooth at idle, slow speed, and WOT. Last week had boat out and wouldn't start, took it back home and missed around with it and finally got it running. Now it won't start at all. It has good spark, it will jump a 1/2 inch gap with a nice blue, snappy spark. Pulled carb off to re-clean yesterday and pulled rope and fuel was coming out of line that comes from fuel pump. Is this a good fuel pump test? When i took carb off it did have fuel in it. I felt like i cleaned the carb really well, used compressed air and carb cleaner, as well as wire. But after tons and tons of pulls the spark plugs were bone dry. I was going to put some fuel in the spark plug holes to see if i could get her going. Any suggestions on where to go from here?

Thanks guys,

Did you take the carb apart or just open it up and blow it out etc...

It really doesn't take much to foul a carb. is there a fuel filter somewhere between the pump and the carb? Are the plugs on in the right cylinders?

Re: Carb getting fuel, not getting to motor

I took the carb apart soaked it in carb cleaner and sprayed out with carb cleaner, rinsed with hot, soapy water and blew out with compressed air. No fuel filter between the pump and carb. Not sure what the right cylinders means, can you mix up spark plugs?

Think he meant the wires not the plugs. Try the gas in the cylinders if you want but it will make it run but won't fix your issue. Is your slow speed needle opened 1/12 turns from gently seated? You might try opening it 1/4 turn more at a time until she starts feeding gas. Give that a try. Best of luck. Rick.

Rick ment to say...1 1/2 turns from gently seated......

He sure did! LOL. Spell check doesn't catch it all does it? Another thought I had after was I think those newer motors like yours had finer threads on the needles so it may need to be out more than I said right from the start. I don't have any manuals newer than 81 and it says 1-1/2 turns. Rick.

Re: Carb getting fuel, not getting to motor

I had it purring like a kitten after i replaced the missing parts on the carb by adjusting the slow speed needle and then it when i took it out last week it just wouldn't fire up. Prior to it not starting up i was actually thinking that maybe it was running too rich since the plugs, which i replaced about two weeks prior were looking fouled already. The plugs are bone dry when i pull them out after trying to fire her up. I'll go back and start from 1 1/2 turns out tonight and see what happens. About the plugs, i bought new ones and put them in yesterday they both look exactly the same to me. Should there be a difference?

I'm pretty sure Leeroy's Ramblings mentions something about the newer ones needing to be out 4 or 4 1/2 turns as well. Ill take a quick peek.

Re: Carb getting fuel, not getting to motor

What plugs were you using. It's possible that you have good ignition voltage but the plugs are fouled. I think you said they were bone dry so maybe this is not the case but something to think about. Try increasing the enrichment to see if that helps. Also, did you change the slow speed bearing or bushing. I forget what it is called but it is a very small piece of plastic that looks like a small funnel that goes into the end of the slow speed jet (after you take the other one that is in there, out)

Needle Valve Retainer. Very good point.(as always) Rick.

Re: Carb getting fuel, not getting to motor

OptsyEagle, when i replaced the plastic carb cover i updated to the carb cover that has the integral plastic post instead of the metal screw. I don't think either has the bearing you're referring to. Here is a link to the carb picture for my engine

Re: Carb getting fuel, not getting to motor

i do have the valve retainer. i thought you were referring to the bushing that goes down into the bottom of the slow speed screw. the only thing that's really baffling me is if the ss needle was set and i was up and running for 3 weeks, why all of a sudden would it not crank now?

I was. Perhaps they did away with that on your model. My 1975 has one that if buggered would prevent the gas, that got to your carb, from getting to your cylinders.

The other issue could be leaf valves. Probably unlikey that both cylinders would be effected. Do you ever see any gas coming out your carb throat into your air silencer?

Anyway, try enriching the mixture and see if that helps.

Re: Carb getting fuel, not getting to motor

I haven't seen gas in the silencer. I'll readjust the air mixture when i get home this evening. Thanks for the help guys, I really appreciate it. Need to get it up and running to take the boy fishing this weekend.

Re: Carb getting fuel, not getting to motor

Ok. When i took the carb off i noticed that after i fill it with fuel there was fuel leaking from around the screws and seals. Not sure if i did this when i put it back together or not, but one of the screws was overtightened and cracked the carb bowl. I replaced it and after readjusting the float and resetting the slow speed needle to 4 turns out of lightly seated she fired up. I was in the process of fine tuning the needle when i noticed that no water was coming out of pee hole. Guess i'll start by running some weedeater wire up there to see if its just clogged up. Any thoughts?

Re: Carb getting fuel, not getting to motor

Run the weedeater wire. Was the water in the tank at least 3 inches above where the lower unit attached to the mid-section (above the water pump)?

Re: Carb getting fuel, not getting to motor

I'm not sure... i'll have to double check exactly how far up it went. If i remember correctly the water was just below the exhaust holes. I had it running on and off for about 5 minutes. Hopefully even if it is clogged i didn't burn up the impeller.

Re: Carb getting fuel, not getting to motor

I think you were correct Optsy. It's peeing now. Dropped it in the tank a couple more inches and it runs fine. Was able to get out on the water on Sunday and fired up in 1st or second pull. All is good, no i focus on fixing her up a bit to make it a little more comfortable.

Thanks all,
