I've been breaking a sweat over my grandfather's old merc 110 for a week now. Finally got it to where it will start, however, it won't stay going.<br />I've checked these things...<br />-plugs are new<br />-engine is getting fuel as far up as the carb float (I've taken apart the carb & cleaned it)<br />-gas tank & fuel line is new.<br />I've even gotten it to run at full power for a few seconds (have it sitting in a big tank of water.) But it never takes long to cut out & die.<br />I'm at loss for what to do other than perhaps replace the plug leads? Any other ideas? Any help would be appreciated...Thanks!
