Re: 1958 evinrude 40 hsp,. outboard runs ruff
Sure of the year? I think they were 35s until 1960. Don't really matter much. Basically the same carb. And basically a basic carb. Not much to them. Most of the time all you need are the gaskets (bowl, center nozzle, mounting) and a float valve. Idle mixture should be about a turn out, high speed (bottom) about 5/8. Those settings should get it running good enough for fine tuning.
