1983 15 hp Rude Intermittent Stalling

[Sailormannj]

I need some help here. I have a 1983 15 hp long shaft Rude. Recently it has taken to stalling when I try to advance the throttle. It has done this on a cold and a warm engine. It even may stall when I am at the "Start" speed and going for a while. Yesterday, when I was about 3/4 throttle, it started to stall, but I gave the bulb a sqeeze and it continued to run fine.<br /><br />When it does stall, it starts up fine.<br /><br />My friend at the dock thinks it is the fuel pump diaphram.<br /><br />This is an intermittent problem, where do I start on this one?<br /><br />Thanks.<br /><br />Paul

Can you repeat the scenario where you squeeze he primer and it continues to run OK?

When it was running at 3/4 speed it began to stall and I gave the bulb a squeeze and it ran fine after that.

It could be the fuel pump diaphram but I think it more likely it is crud in the carb (rebuild the carb) or air entering the fuel line or a clogged pick-up line in the fuel tank. I doubt the diaphram as you said it ran at 3/4 throttle that would indicate that the fuel pump is pumping.

Thanks. I looked in my book to see if the carb has a bowl like the older ones had, bud did not see one in the pics. Thought that there may be water or something in it.
