now i cant get it started!!

Dino89 · 23 July 2008, 12:19

new battery new plugs and even new steering wheel and cable ....just gone to start it after winterising last year put new plugs in and it wont start looks like a good spark but the plugs are bone dry after a lot of trying , is this usual or is something wrong been trying for about 10 mins
all 3 plugs still bone dry just undone drain plugs on carbs and plnty of fuel coming out of each carb

i did all the carbs and plug holes last winter with quick silver winteriser

thanks

i got the prop in an old water tank and theres plenty of oil on the top of the water !

just a thought shoould this be posted in another forum?

take a couple of plugs out and put a small amount of petrol in the cylinders, put plugs back in and try see if that clears it.

Fuel hose on the right way around

Dino89 · 23 July 2008, 15:28

yes only goes one way as its permantly tie wrapped to the boat

Hate to admit to it for a second time - but I did all that a few weeks ago and had forgotten to put the kill cord on ....

Dino89 · 23 July 2008, 15:32

i did check the kill cord as that is exactly how dead it is ,but i am getting a good spark at all plugs

I agree - give in a good prime first!!!

Also could be a choke problem or not enough throttle.

Dino89 · 23 July 2008, 18:17

when i push the key in for choke i hear a click but cant see anything physically happen after priming and turning engine over for a good couple of minutes absolutley nothing not even a little fart!!! it just seems so dead ,when i remove the plugs there is no no smell of fuel and they appear bone dry there is a good spark at all 3 plugs i have removed the carbs all looked spotless inside blew through the jet and checked the float was moving freely
been trying all day the new battery is now on charge the water butt has plenty of two stroke floating on top
i did try priming the blub while my son turned the engine over it went soft for quite a while when the engine was turning over then firmed up after approx 10-15 pressess id guess but still deader than a dodo it does seem as though fuel is not getting to the cylinders but im no expert!!
its a 97 merc 50 it ran fine when i winterised it and run the fuel out in october last year!!
when i cleaned the carbs today they were all full of fuel!! so fuel is getting to carbs!!

codprawn · 23 July 2008, 18:41

It's no good in the carbs - put it into the cylinders!!!

Dino89 · 23 July 2008, 18:46

i did prime the cylinders every time i have tried since mr chappelow said earlier this afternoon
after all the turning over should the plugs not be soaked and smelling of fuel ? beacause even with putting it the cylinders there bone dry sfter giving it a good turning over

Are you using fresh petrol?

Take air manifold of and open the throttles up, is there any petrol squiring out the jets of the carbs?

rib-x450 · 23 July 2008, 19:45

I often carry so Bradex Easy Start.

You can get it from a motor factors, possibly Halfords, or some chandlers.

It is ether based and you squirt it onto the intake, or even remove the air filter and squirt some in, it normally starts anything, but wont fix a problem.

Check fuel is new as well.

I carry it on my boat for emergencies.

Hope this is useful.

will definetly get some tomorrow and give it a try so do i understand you squirt it in the carbs intake after removing air filter box and yes did get fresh petrol first thing this morning
think theres possibly a problem beacause i have tried all day and not had a splutter but will def give that a try
thanks

Dino89 · 23 July 2008, 21:00

hightower will give the throttle one ago tomorrow what does it indicate if fuel does or doesnt come out?

Nos4r2 · 23 July 2008, 21:13

DONT EVER use easy start on your engine. It strips the oil off the internals and can break rings. It's also explosive. It has no place on a boat-ever. IF your engine needs it to start then your engine needs attention and you shouldn't be using it.

Like petrol vapour?

Well if you open the throttle quickly it should actuate a manual fuel/carburetta pump that will squirt a visible jet of neat petrol into the venturi. If it doesn't it could indicate that the diaphram in the pumps gone, but I doubt that both have gone. I was lead to believe this was a common problem after over winterization due to the rubber being in contact with old fuel. The other thing that is common on overwintered engines with carbs is that old fuel leaves a varnish residue in the bottom of the float chamber, this then breaks off and clogs the jets.

I also agree with Nos4r2 and suggest you sort the problem rather than use the addictive either based starters. It shouldn't be nessesary and won't correct your problem.

Dino89 · 23 July 2008, 21:46

the only thing i have realised is my throttle is combined with gear shift so i wont be able to open it whilst starting as it locks it centrally
unless i can open the carbs by the linkage on the outboard will have a look tomorrow this was the first time i have winterised the motor in the 3 years i have had it and i wont be doing it again!
so it could be the fuel pump that has gone faulty are these repairable
or do you have to replace .i suspect it could be something like a fuel pump purely because i havent had any hint of a splutter from it all day which to me indicates a failure to all cylinders
its a 3 cylinder 97 merc 50

No, like nitroglycerine.

Many years back I went out to do an insurance valuation with a diesel fitter on a tractor that had run over a can of easy start. It had blown it on its side and burned it out.

When you start an engine with it the explosion is so fierce when the engine first fires that it can break the piston rings.

Do you not have a fast idle lever?
