9.9 evinrude fails to start

[chelseamad7]

Hi all,
I am now at a loss,model number is E10EETM 1993 9.9 HP Evinrude.I put my engine in a tank for a run for new season,i noticed that there was no water coming out of the telltale.It had run on idle for maybe 2 mins,i stopped the engine.
I bought a water pump kit and a carb kit.
Fitted them when they arrived here in Bulgaria.I bought 2 new spark plugs 0.030 gap. I checked the thermostat cleaned it and reinstalled.I then bought 5 litres of petrol and added 100ml of boat two stroke oil.
I then tried to start it,it ran for 10seconds then stopped.Read in the manuel re fuel/air screw,it was correct.It wants to start
and sounds like fuel starvation,but where?
I checked the compression its ok.
Can someone please help me, thank you all.

Re: 9.9 evinrude fails to start

Try to start with choke if it fires up then turn throttle up a little untill it gets warm it could be alot of things if doesnt start with choke take plugs out and see if there wet or dry try using starter fluid when u first get running dont let it quit if u have to pull choke out in in untill it gets warm if the plugs are wet then maybe its fludding if there dry then spray some starter fluid or gas in cylinders maybe theres dirt that needs sucked tbrough check gas line make sure the bulb is firm then let us know some more

Hi thanks for trying to help me,yes the plugs are wet and u would think its flooding.If that is the reason why does it keep cutting out? How do i stop it from flooding thx.

Re: 9.9 evinrude fails to start

check the output from the fuel pump by either disconnecting the fuel line at the carb or disconnecting it at the pump and attaching another piece of fuel line, remove the sparkplugs to make pulling the rope start easier, you should ground each spark plug wire as well to prevent a stray spark and possible damage to the ignition components, pull the rope start, or use the electric starter if you have it and observe the fuel pump pulses. They should be strong and remain so. Weak or nonexistent pulses and the pump isn't working properly. If that checks out post back and the carb issues can be examined.

Thanks very much i'll try that and get back to you.
Thx again

Re: 9.9 evinrude fails to start

Hi AlTn,
I took the fuel line off the carb,turned engine over with electric start,I timed for 1min. and there were approx 128 pulses they were strong
and constant.So i think the fuel pump is ok.Do you?
RE the carb i can tell you that i bought a new carb kit and cleaned out the carb with compressed air then fitted new parts to carb.I have a manual and turned the fuel/air screw from slightly seated 1 full turn,thats all the info i can give you.Now its your turn what do i do now.
Thank you for helping me.

Re: 9.9 evinrude fails to start

pump output sounds fine...when you had your carb apart did you remove the orfice plug from the nozzle well and make certain it was absolutely clear through the jet?...the float is level with the carb casting when the carb is inverted?...the tab on the float arm is pointed towards the carb body and not the bowl?...was your idle mixture needle 1 turn out when before you took the carb apart?..if the threads on the idle mixture needle are fine, you may have to back the needle out 3 or 4 turns.

If you haven't visited this site yet..google..leeroysramblings.com...and go to his articles on 9.9-15 hp. repair and maintenance. You might also try marineengine.com for schematics of your engine.

Try opening the idle mixture needle first and post back any results.

Re: 9.9 evinrude fails to start

Hi AlTn,
I looked at those 2 web sites you suggested,fantastic advice on there.
I took the carb off again and double checked all the points you said all were ok.I then carried out a link sync and it was out so adjusted and now ok.
I then opened up the petrol/air screw like you said,it seemed to fire up better,so opened it more and more till it sounded ok,i then put it in forward gear,ticked over ok.I cut the engine and let it go cold.Restarted it with choke,warmed up put it in gear again and made final adjustment plus 1/8 th more.
I noticed there was like a type of clang noise while doing the adjustment in middle part of engine,it seemed to have stopped now.Any ideas
what this could be ? i carried out the TDC with screw driver down plug hole,there was no play.I would like to say to you Thank you very much for your help,you were a blessing in disguise,if your ever over in Bulgaria we will have a night out on the beer.

Re: 9.9 evinrude fails to start

thanks for the offer...as for the clang,I dunno...if you hear it again I'd try pushing and pulling on the engine block and exhaust housing to see if maybe the supports or mounts might be loose and a little worn...you may have had some preignition < knock > going on as well

Hi LeeRoy,
Yes it was very helpful and very informative.Iwish i had read a certain paragragh before attempting to remove the left hand side nut from the carb.Yes you guessed it it fell into god knows where,i looked everywhere for it but no luck.Can you tell me where to look and how to get it back please.
Reason being i cannot buy another nut out here in Bulgaria,also it might do some damage to my engine.
This is so true and NOT a joke.
Thank you.

Re: 9.9 evinrude fails to start

are you speaking of the carb mounting nut?...screws onto the intake manifold studs?

 

[chelseamad7]

Re: 9.9 evinrude fails to start

Hi AlTn,
Yes one nut on each side of the carb, they hold the carb on to the intake two studs.
What a plonker i am.
Thanks.

Re: 9.9 evinrude fails to start

you could pull the carb off and inspect the intake manifold, or fish with a magnet as the ones I've managed to drop are weakly attracted to a magnet and can be lifted if you go slowly. Sometimes if they are lodged elsewhere you can blow them out with compressed air.

hi,
I know its not in the intake manifold,tried the magnet attack but no joy,i have not got access to c/air. My main concern that it would not do any damage to the rest of the engine.
Thank you.

Re: 9.9 evinrude fails to start

not likely to ever be a problem
