Re: 1979 Evinrude 140 rebuild sucessfull start but problem......?

Just let me know if you need a phone number on that paint. Thanks for the part number. I've located the kit on ebay for about $15.00. It should be here by the time I get these carbs cleaned,floats adjusted, both reinstalled, new "T" installed, and the link/sync done. Man I hope this solves my problem. I'm just about at my wits end with this thing............ :'(

Alan - keep after it, sooner or later you are going to have a motor that runs like a champ and will last you a very long time. Personally I love working on these things but I know it gets frustrating especially when it interferes with your fishing time and your beer $.

I fired mine up for the first time yesterday - it did not exactly start easily and it back fired several times while I was cranking it so I am thinking it needs the timing adjusted and possibly a "link and sync".

If you can possibly summarize your findings on how to best link and sync it would be much appreciated.

No problem at all 79Rude115. This is as per R.Johnson here on the board and, if followed step-by-step, works extreemly well. Refer to Pages 2-16 and 2-17 in your manual to see what he is referencing if you don't understand the proper terminology of what your looking at...............Good luck!!!!................. ALAN

PS..... Follow the manual on the throttle valve and choke valve syncronizations. Their the easy parts. I went by the Joe Reeves meathod on the WOT timing and it's really close. Don't forget to test the spark while your at it. I built my own spark tester in about an hour.






Starting from the beginng, these adjustment's can be made easier if you disconnect the throttle cable to get it out of the way. Move in the idle stop screw until the throttle cam is out of contact with the rubber roller, loosen the throttle link screw so that both carb's snap fully closed, then tighten screw. Advance throttle cam until it contact's rubber roller, it should contact top mark, or embossed mark, "same thing" so that it is centered on the roller, loosen screw on roller, and adjust if it is not. This will make the adjustment close enough. Start the engine with the trottle cable still disconnected. With a timing light on #1 cylinder, screw in idle stop screw, and adjust until you are at 4-6 degree's B.T.D.C. Now remove the cotter pin, and washer from the throttle cam yoke, this is the white threaded yoke on the bottom of the cam, remove it from it's pin, and screw it in, or out until top mark, or embossed mark just touch's rubber roller, and replace washer, and cotter pin. Now adjust idle speed to 700, to 800 if running on muff's. (mine idled at 1400 on muffs and 800 on the water) Replace throttle cable, and adjust trunnion until the throttle linkage is just back to.the stop screw with slight tension. Shut the engine off, and see if the throttle goes completely open, and back to full idle. This should complete the set-up

Any word on this yet?

I finally got mine back and am hoping to take it out to verify it's all good. I'm curious where you stand on yours.
