i have got a fourtrak engine thats been sat for a few months and it started fine first time, but there is blue smoke comming out the exhaust when you rev it. when idle it is as sweet as anything but once you rev it there is blue smoke from it, this was even after 20 mins of running it. any ideas on what might be the cause of this and how to fix it? to be honest i have not got very good mechanical Knowledge but have got a friend that will help out on anything that needs doing, or are we getting a little to ahead of our selves here?
