First let me say this my first post and just joined today. I've read thousands of forums on here. Ok. I have a 1982 Evinrude Xp150 and its not running good. It misses at idle on muffs in the driveway as well as missing at the lake. I've rebuilt the carbs twice in the last 6 months (second rebuild was dipped for an hour each) as well as rebuilt both fuel pumps. I've also replaced all the fuel lines from tank to carbs and inspected line inside the tank with pickup screen. looks great. Now here's what its doing. At idle on muffs it misses and sound rough. if you push the key in (primmer) it dies. Duh. Now same thing but at higher RPM (around 3000 rpm) still on muffs it runs smooth with out missing. Sounds wonderful. Now on to the lake tests. Idles in gear fairly decent until I punch it to get on plane. Misses and pops until i get on plane then smooth. Smooth as in WOT but only going about 30mph and around 3000 rpms and missing from time to time. Now here's the funny part. If I push the key in (primmer) it comes alive. 5000 + Rpms, 45-50 mph and runs smooth. I don't know if the primmer solenoid is bad and leaking to mush fuel causing it to miss and be sluggish. Everyone keeps telling me it's a fuel problem but I'm starting to think it's not. Can someone please help me. I've spent 2 years fulling restoring this boat and would like to enjoy it. I don't know mush about power packs and the ignition system parts of it, but wondering if I need to be looking into that a little closer. Thanks and any help would be greatly appreciated.
