I have a secondhand bike with a 66 80 Chinese engine of some sort. It has been difficult to get the idle adjusted with the screw for a few days.
I think the engine seems to be running rough for the last few days, but don't know for sure how these should sound when riding it.
I previously had an exhaust flange leak, and I thought it was sealed with a new thick gasket as recommended here. Now I found some fresh oil on the TOP,
front, corner of the head near the cooling fins. See pic. Plug seems tight and the head/exhaust bolts are tight, but I didn't torque the head bolts (they were installed by the builder). Does this seem like a blown head gasket? I can't find much sign of oil on the front of the engine or around the exhaust manifold. I have some spare gaskets on hand if needed, but thought I would see if anyone could think of other possibilities to consider first. Thanks for any thoughts and help on this. John
