Do I need to become a "carb" man?

[martyscher]

I will be running a new 2001 40HP Johnson 2-stroke on various mountain lakes between 5000 and 9000 FT. This summer it will on on mid west lakes from 400 to 600 ft.<br /><br />I am not that excited about messing with a brand new motor, but on the other hand, I don't want to settle for poor performance and fuel economy and I do not want to possibly damage the engine, or create a lot of build-up or plug fouling due to grossly incorrect fuel/air mixtures.<br /><br />Can I get some insight on how to manage this motor in vastly different altitudes, especially in the area of jetting and carburator adjustments.<br /><br />I do have experience with carb ajustments, but not much with outboards (except for a 40's Neptune that leaked more gas than it burned).<br /><br />Any input is appreciated.

Honestly that is a new motor. I would contact the dealer about the jetting differance. The older outboards had jetting charts for motors ... (I have a book up to 1990).<br /><br />Bob
