" The Universal 3 cyl 22 hp in
" The Universal 3 cyl 22 hp in my newly acquired sailboat has a 'rough spot' in the middle rpm range. I do not have a tackometer, but it runs smooth up to 1/4 throttle, then rough until it smooths out again at a little more than half throttle. I get hull speed at a little less than half, so the rough spot seems to be right in the range I would like to run. It's not a bad vibration, more of an irratation from the noise. It runs real sweet at a high throttle setting. It is the same in or out of gear, although a little more pronounced in gear. The engine is 15 years old and has less than 1500 hours [per previous owner]which is about normal for a sailboat. It starts easy, and runs clean otherwise. It gets run about 2 hours each trip out. Fuel and filters are clean. If it were gas, I'd be changing points and plugs I think.
Run it and enjoy, or try to remedy?
