so there i was headed down the rive to the ocean to do some late season striper fishing. When my cousin relized we forgot the chum. made a quick left turn back to the dock when the motor just started chocking then got all power back. kept head back and again lost all power... came back and agiain this time made it back and brought the old girl home. pulled the cowl and noticed greenish fluid coming from carbs. pulled the plugs checked them, then started motor pulled # 3 wire no change # 2 wire no change # 1 wire and got zapped and motor died. switched all the plugs around started same thing running on one cylinder took a old plug and checked for spark on #2,3 good spark and no problems before. yesterday i was flushing the motor and for got to hook up the fuel hose ran the motor out of gas. so im thinkg carb issue the motor had sat for 2 years without running so were should i start on the carbs 3 days ago ran the motor for 4 hours no porblems. should i pull the carbs and see if a float is stuck jet is clogged or is there a way to test if the carbs are getting gas to #2 and 3 any help would be great you guys are the best thanks Josh i missed the fishing good day for it

Take a squirt can with some premix fuel in it, start the mtr up and squirt some fuel into the throats of # 2 & 3. If they pick up and run you got some carb rebuilding time coming.

Yes, but you'll know when you play with the squirt can.

How did you check your spark?? I hope it wasn't with the spark plugs. The spark should be able to jump a 7/16" open air gap on a spark tester. You can buy them at most parts houses for $10.00 or less.
