What to do now???? Help

[elderBombadil]

K I rebuilt the carb reinstalled it and ran it for 10-15 minutes in the tank and it ran fine. Tonight I came home repair a leaking gasket(on the themostat cover) and put in new plugs (yes I gaped them correctly.) I get out to the lake get it start, get going and it just quits. I can not get it started. The best it will due is turn over a little bit if I have the choke pulled out but it would not stay running no matter what I did. Whats my problem now? I am stumped any help you can give me. Its a 1961 5.5 HP Evinrude. Yes I have a clean tank of gas.

Check the spark at each cylinder elder...Spark should jump at least a 3/8" gap with a hot thick spark. This engine has two points and condensers under the flywheel along with two ignition coils. Either may have failed.

Specifically how did you rebuild the carb?

Well I followed the directions at this web site. http://outboard-boat-motor-repair.c...hnson 5.5 HP 1954-1964 Carburetor Tune-UP.htm <br /><br />I put all new seal/gaskets, new float and pins and cleaned all metal parts with carb cleaner.<br /><br />An update, taking some of the advice I have gotten. I poured a little gas directly into the cynider then replaced the the plug, and it fire up then quit once it burned up that gas. So it appears that I have no gas getting to the cylinder. I know that when I press the fuel bulb that it shoots gas thru the lines. So do I need to rebuild the carb or do I have a stuck float? Any advice from you guys would really be helpful since this is the first outboard I have ever worked on.

Get a "Windex" type spritz bottle and put some mixed gas in it from the gas tank. Spray some directly into the throat of the carb. Note: don't cheat and use aerosol "starting fluid", it's very bad on 2-stroke internals. Pull the rope. Does it start and run a little bit? If so then your nice clean carb got gunk in it already, the little orafices are plugged, and it can't feed gas to the motor. Gotta clean it again, not major just blow out the orafices (groan). <br />Another note: old rust, paint flecks, crud accumulates in the gas tank and fuel lines. The carb orafices are real tiny. The crud gets stuck there. Go to the hardware store and get a few feet of new small-engine fuel line (remove your old lines and measure the length and inside diameters) and some new fuel line clamps. Also get a cheap "inline" fuel filter for the correct inside diameter of your main gas line (from the tank). You can do all this for $20. Good insurance. Now everything's clean and new in your fuel system and the smallest passages are the membranes in the fuel filter, not the orafices of the carburator. The evil gunk is stymied.
