My standard air filter has a connection to the rectangular cover for the valve springs, I just ordered an air filter from bmi and the adaptor that supposed to go with it doesnt look like it has a connection for the cover, any ideas?

We normally just leave it hanging. You could attach a piece of tubing to it and run it down the frame if you like ( this would be to prevent a mess if any oil came out).

Early on I made a plate to cover this, installed a fitting and ran a hose over to a collection tank. I was able to keep an eye on how much oil was pushed out. Later I hooked this line to a vaccum fuel pump. This created negative pressure in the base of the engine which gave more power. As long a ring seal is good, this is a power adder.

Forgive my ignorance but how does a vacuum fuel pump make a vacuum in the crank case? I have thought about creating crank case vacuum for more power but was not sure how to do it on a mower engine.
