Carburetor leakage

by moshe rudko in 2 Stroke Technical Questions 7 years ago

Hello,
Is anyone have an idea how this leakage can be fixed?
I rebuilt the carburetor after replacing parts according the maintenance schedule and a while after it started to leak.
It happens only in one of the two.
Please see the attached pictures for better understanding.
Thank you in advance,
Moshe

Do you have oil injection installed?
If so, I suspect the injector connected to that one carb is leaking injection oil into your carburetor body.

It's the standard fuel-oil mixture system that comes with the 582. I don't premix the fuel before refueling. So, I guess that the curb gets already the mixture.

Most two cycle engines exhibit a little intake fog through some part of their performance curve. A little condensed oil sitting in one Carb and not the other could be a result of cowl airflow, air filters, Carb syncing, ignition breakdown or a mechanical /wear issue with the intake tract.

Take a close look at the oil injection pump just above the carbs. I suspect it is leaking into the one carb. It looks more like 2 stroke oil than it does fuel.

Did you ever figure this issue out? I am having the same issue and think its the rotary valve oil seal. I do not have oil injection and can see a leak when I removed the intake cover and rotary valve.
