I AM LOOKING FOR A SERVICE MANUAL, REPAIR MANUAL ANY SPECS ON THIS PARTICULAR MODEL SUCH AS COMPRESSION IN LBS., ETC. A FRIEND GAVE ME THIS 15O MPH, YEAH, BLOWER A FEW DAYS AGO AND I WANT TO CHECK IT OUT BEFORE I BUY A NEW STARTER COIL SPRING FOR IT. IT LOOKS UNUSED BUT HE SAID IT WAS LEFT AT THE CAR DEALERSHIP WHERE HE WORKS, SEVERAL YEARS AGO. THANKS, J.J.
