Re: Carb Jets

The carbs might be a different size. Changing jets only richens or leans the air/fuel mixture. It doesn't increase the amount of air/fuel flow

Re: Carb Jets

I just put carbs from an 86 150xp evinrude on a 77 175 evinrude, the carbs were 1/16'' bigger, so i left in the bigger orfices to account for the more air flow, you will wanna run a little on the rich side. Unless you race. Running rich will give more fuel/oil mixture. You want more oil if in doubt.
