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 ?

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.


Does running
out of petrol lead to problems with an outboard ?

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


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

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.
