first off you dont have a lot of info to give a real answer to your question
older engines are not rated on any one number like blood pressure - its how different is the engine's compression front to rear - Note - cranking speed will change the number ie battery condition also plays a roll - type of oil in the motor 50W 70W and has it sumped some of it
< running in water up to your ankles you can a lot faster than you can up to your knees -
My opinion if the numbers are with in 10 pounds of each other -- with the throttle wide open and a fresh battery and no oil in the cases that does not belong your good -- just my take doing this 2 weeks now -- johnjzjz
