I have a silver pro series model 10323 2 cycle E, serial # 9932708 that has run great since purchase in 1999. I love its light, powerful, easy maneuverability, since I have a left arm but no right arm (lost in accident 60 tears ago).
Last season some oily substance was coming out of the exhaust. Does this mean the rings/ cylinder wall are worn out? I haven't done a compression check. I'm thinking of a new shortblock if such exists.
Any suggestions? Thanks

Sounds like you may be mixing your fuel/oil ratio wrong. Too much oil, have you changed your brand of oil? Could you be using an oil for water cooled engine instead of an air cooled engine. I would recommend using a synthetic such as Opti 2. May take a couple of uses before it clears up. Also, if you haven’t done so change the plug.

Unburned oil in the exhaust not uncommon for two cycle engines, especially if the fuel/oil mixture contains more oil than the manufacturer recommends.

Hello,

It's pretty common for the Duraforce carb to leak at the needle valve causing fuel to pool in the transfer chamber and eventually into the muffler. You could perform a compression check, most of my Duraforce engines pull 105 to 115 PSI.

Regards
Jeff
