curious about evinrude carbs

[thunderxky]

i have a 1973 70hp evinrude, model number is 70673d. i have 3 carbs, all 3 have what lookes like, a adjusting screw on the top center of all three. the deal is all 3 screws are seated, and go down in a hole tight, can someone tell me what they are for and what they do??? there are no more adjusting screws on my carbs except those.. thanks

I believe that the '73 on up did not have ajustable carbs. The slot is from a screw head that covers the fixed idle jet.

Thunder.... Seahorse is correct. The carbs are not adjustable. The screw you speak of is simply a air block that covers the fixed brass slow speed jet and it must be seated firmly. Same holds true for a 1976 70hp model.

If you want a general repair manual, click the "Repair Manuals" icon in the lower lefthand corner of this page. You'll have a choice of either Clymer or Seloc. If you want the oem manual go here:<br /><br /> OEM Manuals <br /><br />c/6<br /><br />Hooty

Lets keep in mind we are working with a 1976 70 hp not a 1973 65.

hello Dhadley! i just thought mine was a 1973 model buy the 73 in the model number, am i wrong?? here is the model number again 70673D. if i got the year wrong, thats why its so hard for me to match up to a manual. i do know for sure that it is a 70hp, not sure of the year though, can you verify this for me Dhadley or enyone... thanks thunder

Dhadley's right. There are no '73 70hp engines, just 65hp. Your model number checkes out as a '76 70hp.
