Stalling problem - Dodgy Mix ?
 

Hi,

I have an Evinrude 70 which has perfomed fantastically well for me.
However, I went on an 8 mile journey through rivers and canals on
Saturday and ran out of petrol towards the end. I refilled the tank
from the spare and it started fine. However, since then whenever I
lower the revs it stalls and won't restart without maximum revs. I've
noticed that when it starts to slow down in revs and is about to
stall, no amount of throttle will stop it from dying. Could it be that
I've got the mix wrong ? Would too much oil cause this ? Does running
out of petrol lead to problems with an outboard ? I did put new sparks
in a couple of weeks ago, but have had no problems at all until I ran
out of petrol so I'm pretty confident that they are not the issue.

Thanks in advance for any advice you can give me.

Ian

More likely some scum that was in or formed in the spare tank may have
gummed up the carbs. When I ran small outboards off of 6 gallon tanks, I
occasionally poured way too much oil into the mix (by a factor of two or
three on occasion), and aside from a bit more smoke, no harm seemed to
be done.

Not usually with a two cycle...many owners of more portable two cycles
run their engines dry when removing them from their boats for transport,
and they do this frequently

Thanks Harry, would running the engine at full pelt clean out the
carbs or do I need to "get a man in" as it were ?

Thanks again

Ian.

Check the filter and carb. Sounds like you may have sucked up debris from
the tank bottom when running it dry.

Good luck.

You're slipping, Harry. He said he tried to run the motor on petrol. It's
supposed to run on gasoline. Apologize to the man and provide him with
correct information.

Thanks to you all for your comments and advice. Being a total novice
with engines, could you possibly point me in the right direction as to
how I remove & clean carbs ? Maybe a web site with simple, easy to
follow pictures exists ? I've looked far and wide, but if you guys
know of one I'd be grateful.

Thanks again for your help.

Ian.

Yes, thats just what we need...more pollution from ignorant red necks,
who cant seem to grasp the simple operation of a measuring cup.

It also fouls plugs, but we didnt really expect you to know that,
since you never even ran any type of boat motor before.

Again, our village idiot confirms he knows nothing. Running 2-strokes
dry is a bad thing...it starves the bottom end of needed lubrication,
and it can dry out diaphrams as well.

I think it *too* funny when this clown goes out on a limb with his own
words (as opposed to his normal web site cut-n-paste) to try to prove
he knows something abouts boats, but only ends up confirming he knows
nothing, and is a liar.

What a joy it is to read this clown... :)

A workshop manual is worth it's weight in gold for stuff like this.

Since you have 2 carbs (guessing) it's important that they are
synchronized, the maunal will explain the setup.

Do one carb at a time and be methodical, if you get stuck, refer to
the other carb. It's not a complicated operation. Also, write down ALL
your adjusting screw settings (e.g. nuber of turns to full closed)
this will facilitate your fine tuning later.

On 2 strokes with multi carbs, it's important that both are supplying
fuel and the vital lubrication to the moving parts. Don't spent time
trying to crank it if it needs work, you'll be doing all sorts of
damage.

Good Luck.
