Hi all, kind of a long explanation. Had an issue with this motor a while back, wouldn't idle or throttle up. New fuel (premium) and finally took it out this weekend. Fired right up and idled perfectly, let it warm up, put in reverse and it stalled. Restarted and worked as is should. Put full power across the lake, slight bog but picked up and went. Next morning, fired up and worked as it should, until trying to move to another spot after about an hour. Started up, let it run for a short bit, put it in gear and throttled up and it stalled. Tried several times, and finally picked up and went.The same issue throughout the day and also today. I have to restart several times and put the hammer down until it finally moves. When it goes, it runs perfectly at high and low speeds. I'm leaning to dirty intermediate (low speed jets) or possibly a failing fuel pump. Looking for anybody that has had the same issue or a little more insight. I'm gonna be pulling the carbs and running them through my ultrasonic cleaner. Prefer not to pull everything apart if I don't have to. Thanks in advance.
