Newbie...a couple of questions

[pbritt]

I inherited a '65(?)Evinrude 60 HP outboard.<br />It does not idle properly. When I put it<br />into forward, the motor dies. I turned the<br />idle screw clockwise and realigned the<br />throttle cable trunnion, as indicated in the<br />manual. I got it to run, but the idle still<br />sounds slow and weak. Any help would be<br />appreciated. The carburetor has been <br />completely rebuilt a couple of weeks ago.<br /><br />What other problems should I expect with a<br />motor this old? Should I have it completely<br />overhauled when it is stored for the Winter?<br /><br />Thanks for your help.<br /><br />Pete Brittain

Re: Newbie...a couple of questions

Probably your best diagnostic tool at this point might be a compression tester. Mark which plug wire goes where with some masking tape wrapped around the wire and marked with a felt marker. Now hook up a compression tester on one plug hole at a time with all the plugs removed and write down the readings while you turn the motor over with the starter.<br /><br />What the numbers are doesn't matter as much as their relationship to one another. You want the numbers within 15% of each other. If that reads out ok then you might want to double check the points in the ignition.<br /><br /> I've also heard also that some of the older OMC's will sometimes lose the crankshaft seals making for hard to idle and poor running.
