Nice 1st post on the forum..
but i don't think anybody here was saying it was a 2 stroke anyway.
And as far as bottom end vacuum leaks, i don't think there really is such a thing.. a vacuum leak is a vacuum leak.. a crank case technically should(doesn't have to be) not be vacuum ..
The only reason it typically would be vacuum, is for enviromental reasons, because those require the crankcase breather to vent into the intake..
and it typically does that through the vacuum plumbing.. And that's what causes the crankcase to have vacuum..
Any air escaping in the crank when it should not, will affect the vacuum system.
Which might cause unmetered air to go into the intake, and cause a lean running condition..
That has nothing to do with 2 stroke at all..
