1974 - 70HP Evinrude Problems ironed out.

[Uncle Fred]

Back a few weeks I posted a "loss of power"<br />problem. Here's the follow-up...<br /><br />I found a bad lower ignition coil. <br />Replaced it and after a few minutes running<br />time I'd still loose power. Followed the book<br />on checking out electrical items. All seemed to<br />check out.. Removed the plugs and clamped them<br />to the block, darkend the garage and cranked the<br />engine. Lo'n behold, after a minute or so's turning the bottom plug began giving weak then<br />intermittent spark. Installed 1 new power pack.<br />Took it out on the lake and STILL no power. <br />Back to the garage. To shorten the story, the <br />lever that advances the timing via spring action<br />from the throttle/shift wasn't moving freely. Removed, cleaned and lubed. Then I found a small<br />piece of black rubber, evidently from when I put all new hoses on, lodged in the float valve orifice of the bottom carb. Back to the lake after a short run with the muffs on and she now<br />flies along like a brand new one....<br /><br />Uncle Fred
