I have a 97 50 hp evindude model E50ESLEUS that has a miss from idle to approx.3200 rpm's. I can see the motor cover shake and can feel the miss in the steering wheel and in the console. The following things have been done or checked:<br />New champion plugs gapped to specs.<br />Checked compression-140 lbs. in both cyl.<br />Strong spark to both cyl.<br />Link and sync checked. <br />New fuel hose and primer bulb.<br />Cleaned and rebuilt carbs twice. <br />Tried new ignition coil-no difference.<br />Tried new power pack-no difference.<br />Ignition timing is set at manual specs-19 degrees BTDC.at 5400 rpms.<br />New fuel tank-old one had gummy deposits-carbs were free of any gummy deposits.<br />No evidence of water in either cyl.<br />Have adjusted idle mixture needle valves many times-cannot solve miss problem.<br />No evidence of loose or broken hoses.<br />Reed valves do not appear to be damaged.<br /><br />The idle mixture valves on both carbs must be turned out 41/2 to 5 turns for engine to idle- manual calls for 31/2 turns out.<br />I have spent many hours trying to solve this problem so any help will be greatly appreciated.
