I had a bunch of pals drop by today.... so Brad and I being smarter then
your average couple of racers conned them into helping us yank out the Mule
Motor and get the engine bay ready for the Rodeck....

When we got the engine out of the car we did a leak down check on it... took
the left gage to 100 psi and the right gage usually ended up on around
95.... then we stuck on the cylinder and checked the Percentage of leak with
the Piston at TDC..... bottom line we had 2-3 that showed more then 10% leak
coming out of the exhaust valves.... ( if you held your hand over the
exhaust port you could feel the air coming out....

This motor was rather Rich when it was running.... any thoughts on maybe
coking up the Exhaust valves?  Keep in mind this test was done DEAD COLD....
would that effect the outcome?
