The reeds are located between carb & motor, just past the carb boots (inspect carb boots) The "reed cage" actually sits in the jug, pull them out & look where they make a seal (plastic on plastic) or (steel on plastic) The only crank seal you will be able to test is the pto (clutch) seal. Spray around the back of primary clutch, where the clutch attaches to the motor, that is were the seal is, if you can get it to at least sputter (with this method) chances are the other (mag side) is toast also. Or you can do a leakdown test, that would tell you for sure, to do this you must block all openings to the motor exhaust, intake & plug holes, add air into both cyl with a gauage on one cyl monitoring the (leakage) some models might require some special attachments. Good luck Where you at in minne?
