You aren't going to get any help unless you give us a lot more info. We need to know things like: model number of your unit, model and serial numbers of the engine, what color is the smoke, is it coming from the exhaust or breather, has it recently been service, etc. I am pretty good at helpingto solve problems, but due to a recent rush in postings, my ESP is not working properly and the government has shutdown my access to the secret spy satellite, so I can see what you are talking about. Any help you can give me would be greatly appreciated, until my satellite connection is renewed, so ICANN fix it.
