Well the motor was doing great until 2 weeks ago. My Dad came down to visit and we headed out to the river. Everything was fine on our trip until the last couple of spots. I started throttling down as we were getting to our spot and preparing to anchor. As I throttled down, it just died. It never does that. I could restart it with the warm up lever up more than usual but if I just moved the lever down, it would die. As long as I put it in gear before it idled all the way down, it would go. I got home & checked the compression. 112-118 on all 3 cylinders. I hadn't taken the boat out in a couple weeks but took it out again yesterday. The only difference between yesterday and 2 weeks ago was that occassionally I could throttle it down slowly and it would idle for maybe 10-15 seconds, then abruptly die. I was thinking maybe a float was stuck or something like that. Today after church, I removed the carbs, opened them up and everything looks good & clean inside. Float moves freely and so does the needle valve. Although I haven't taken the needle seat out yet. When I removed the carbs, I noticed the coupling assembly broken. I don't know if I broke it taking the carbs off or if it was already broke. For those who don't know what that is, that's the part that connects the top carb to the bottom carb (this is a 3 cylinder, 2 carb motor). If this was getting weak, that would throw off the synch of the carbs. I don't know if that would have just happened all of a sudden though. Anyway, I've got at least that part to replace. Any other ideas? Thanks a lot!
