Make damn sure you're not giving the motor any gas while pushing the start button. This will increase compression and make it harder to turn over and wear out your starter prematurely. Also, avoid using the enrichener at all possible costs. Some may refer to this as "the choke", but it's not a choke. Many have experienced fouling of plugs when using the enrichener. Most never use it. If it's still turning over hard, maybe it's time to look at getting a new battery. Have you done your intro yet? Inquirey minds want to know.
