Hello,
I just installed this motor in my car and fired right up for 10 second and cut out afterwards. I tried starting it again and the flywheel is stock. I took off the motor and took the clutch and flywheel off and everything is perfect. I noticed some oil coming out the front bearing and crank has about 2-3mm movement in and out. I tried spinning the crank and it makes a metal to metal noise.
I also took off the carb and noticed bunch of orange color silicon or something else stock on the crank. Please see picture.
