I took my Johnson 90hp,199,Model J90PLEEB,Serial <br />04671325... to a dealer last fall to have the engine prepared for winter(cost $300.00). When I try to start it, it will not start. I have fire to the plugs, new gas, and a good battery. When I called the dealer I was told that I needed to have the carbs cleaned and kits put in them at the cost of around $400.00. I would like to do this myself. Do you folks with experience, suggest that with the help of a shop manual I might be successful? I"m just an old farmer, and have maintained our equipment for years. I have a complete shop and time to do the job... Much more time than money.HA./. Hope that I will hear from you and thanks for you time. Paul
