Oil in water with bubbles (larger than normal )

Postby Johnny Honwave » Thu Jun 15, 2017 9:14 pm

Hi
I am back with another with question. After you kindly pointed me in the right direction with my friends prop problem.
I have had problems starting it and it has run very intermeditant. Changed the ignition coil new plugs. But when I was last running it there were larger than normal bubbles in the wake with more smoke than i normally get. Which when she's been running and warm nothing really is apparent.
I have enclosed I hope a short vid of it running.
The oil in water has a strong smell of petrol init along with oil residue. Seams to start ok but the plugs get oiled up so becomes harder to start each time.
Thanks again
John Honwave

First thoughts...
You have the bee's knees of outboards there... :clappy

Now to the issue :lol:
Not knowing the history of ownership etc, i'd take a wild poke at the oil mixture you're running is incorrect or possibly using a wrong grade of oil.??
If it was a four stroke i'd be very concerned, but as a two stroke engine is a simple design and only lubricates it's internals through the oil/petrol mix it kinda points to that straight away imo :LMT

Do you have a manual?
What pre-mix are you using?
what oil are you using?
Do you use fresh fuel ?

Hi
I am using fresh fuel. Oil used the same for years.
But when you say correct amount it makes me wonder did I put the correct amount in that last mix ,it's a thing I do carefully but was I distracted did I put to much in ???? It seams that way.
I will do a test and get new fuel and measure oil again. See what that does maybe st before I can get to do it.
I will report back unless someone else has something else to help me.
Really appreciate it

Just by the few seconds that you had it running, i would say that it's the carb setup.
It's kicking a lot which could indicate that it's running rich on the idle jet and it's being kept running with the tickover adjustment.
Very difficult to diagnose without being there, but if your oil mixture is correct then this may point towards the amount of unburnt oil in the water.
Dose it transition to main jet smoothly or does it feel like it's bogging down before it rev's up?

When I had it on the water, yes it did bog down then won't accelerate, then it would suddenly go but it got worse to the point it won't accelerate at all just chugg

Sounds like it's flooding.
I'd give the carb a good birthday :D
I find it these situations that it's best to start again rather than trying to adjust the carb from where you are now.
If you are up to the job strip,clean and reassemble the carburetor.
If not just put the engine in for a good service :thumbsup
