To know for sure what engine you have, you are gonna have to take the starter off. Write down the casting numbers and post them here. You can tell what balancer is on the motor without taking it off. Look at the counter weight on it. If the counter weight does not go at least half way around the balancer, it is a 28 oz. If the counter weight is almost as big as the outer ring, then it is a 50. If you know that the motor runs and doesn't vibrate, then you can go by the balancer that is on the crank. But if you don't know this, we are gonna have to know the casting numbers.
