Ok, on the Evinrude 48 eslcus twin -- vintage of 1987 -- that I bought recently, I found that the carbs do not match any numbers or pictures in the repair book. It is a bit of a chore to get it tuned right without knowing what they came off of. I just rebuilt the carbs and got it running, but not at the settings given in the repair book -- by a loong shot. The working setting is 3/4 to one turn open, seems way too little, but what the clymer book says is around a full turn more, and that is way too rich, won't idle at all.
iBoats doesn't seem to know just what they are, and I'm not sure I want to call the local dealer, and get more of a run around on that issue. However I sure do trust you folks to be able to find out what I have -- and maybe an idea of how to set the carbs and a bit better timing settings, with these non-standard parts.
The serial numbers are top --- 318505-D2
lower -- 318505-D4
Yes they do have adjustable needles in the main venturi area, which is what we adjusted. Doesn't look like anything else except the idle adjustments, and coupled throttle linkage. I can send photos, but maybe with an idea of the year, horsepower, and model, I can hunt it down on line someplace. Gotta be someplace, maybe they are for a different power motor ?? Might have got the timing off a touch in remounting, but can't be by much, it just has more vibration now than before, at idle (1200 rpm) but runs well at higher speeds, thats on a "muff".
Thanks Again, Cal Just learning -- best wishes to all for a great summer !!
