update
I have been seeing on other forums that this is a fairly common issue. They're saying that at higher rpms, the Carb is pulling in air so quickly that it is creating a venturi effect which is creating a vacuum within the airbox sucking the oil into the cylinder. This seems very accurate with my issue. The fix that I've seen suggested has been a fitment of a small breather on the vent. Tips eliminates the pull on the vent tube, but I'm slightly concerned that this vent was placed there with more of a purpose than emissions.
Either way, I will be rebuilding the top end..I have ordered a rebuild kit that comes with a head gasket, piston, piston ring, piston pin, cylinder, cylinder gasket, air filter, and fuel float for 204 shipped. The second two are needed repairsthat I decided to get parts for while I was already paying shipping. The whole rebuild kit was 160 just for reference.I will update again as soon as I receive the parts.
Any opinions on the breather idea?
