Just bought it, drove it for a hour ran great. Then started with a rattle an loss of power, found and oil leak sprayed all over the prop. Distributer cap cover and probably clogged up some, decided to cut to to chase and do a compression check, all cylinders are 150, except #2 is 100. What causes this? Did I buy a motor with a blown cylinder or did it happen with in the first hour??
Seller suggest dropping a new motor in.
