Just thinkin out loud. Could a crank seal with less pressure at lower rpm act like a vacuum leak causing high idle, then at increased rpm with added case pressure have a reverse effect and rob the case of pressure hindering fuel transfer hence poor top end performance? I've used the soapy water test when replacing gas appliances to check for gas leaks in the plumbing joints many times, but never dawned on me to use it for crank seal test. It amazes me how I can overlook such simple logical solutions for a task. Thanks again Jag.

Exactly right Gary, but often leans out full throttle and causes burnt pistons. Pipe effect creates vacuum at high rpm andair is drawn in.

So if your air\fuel is set just right on a engine with a reed valve and a well timed expansion chamber a crank seal leak could be real bad on a engine real quick. The two stroke is a interesting beast.

2 strokes are finicky...... 4 strokes are smooth running with any type of weather or not even tuning them. Nature of the beast

I like 2 strokes because there is less to go wrong:p

I just went back to read Jag's comment on the effects of reed valves and realized I was thinking backwards. I'm on the reed valve learning curve.
