Re: '81 50hp stalling and rpm problem: Video included for you master mechanics

I love to learn...after I had hastily disassembled the carb, and declared that it AOK, I went to my manual. That's where I learned that that little screw with a hole in it was the main jet...and that bit of gunk clogging the hole in the jet was a problem.

There was a tiny bit of room for gas to pass through, but not a lot. This probably explains the bogging issue. I think the reason it opened up after I used the SeaFoam, etc was because the junk had fallen down into the bowl. When it died on me, I had just hit a wave and when I came back down, I instantly lost power. Call me a genius, but I think that the jumping motion caused the dirt in the bottom carb to be stirred up and since it was at WOT there was a lot of suction and you know the rest.

I think I'm on the right track...I'm just kicking myself for tearing the whole carb off...all I would have needed to do is drop the bowl and clean the jet. Everything else is perfect....

Just thought I'd update:

I re-assembled the top carb, checked the bowl/jet on the bottom, put it all back together and she runs like a champ. Ran it for about 1.5 hours yesterday. Behaves wonderfully at all speeds

Thanks for all your help. Now I know how to rebuild a carb (rather easy, actually) and feel a little more able to diagnose and repair future problems.

Being out on the lake is so much fun!
