[QUOTE="mtntop, post: 448885, member: 21789"] Hi, I have a 1990 2 stroke 25 HP merc with a .076 dia carb jet. I purchased this engine in Iowa and use it here in Colorado above 8000'. I rebuilt the carb, it starts but runs very rich at altitude. What do you guys think will happen if I run a .044 jet from a 20 HP merc in there? It will run leaner, which is what I want but how can I tell if it is too lean? I don't want to burn up the engine, it is like new w very few hours Thanks for your insight! [/QUOTE]
