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