Hi everyone. I just received my new 6hp 4-stroke tohastu motor (same as a nissan). I am having some problems with it that I hope someone here knows what is going on. I setup the engine to be ready to get broken in with the external gas tank and motor oil. I realize it is suppose to vibrate during the break-in period in so When it started and was vibrating like a 2-stroke I paid little attention to it. After 10 minutes in idle, I attempted to increase the throttle but it did not respond. I could not get the engine to rev up by throttling up with the handle. When I throttle down the engine promptly shuts off. I checked under the cover and made sure the carb, choke and gear linkages are all working correctly and they are. When I attempted to shift into gear it will go and push the boat for a couple of seconds and dies immediately after. It has no problem starting back up but the throttle persistantly refuse to throttle up. I checked the plug and even swapped in a new one and that doesnt seem to help. I can't seem to find out what the problem is and I am pretty sure it is not normal for a brand new, out of the box motor. Please help. thanks Here is a video of the motor on the boat idling: http://www.youtube.com/watch?v=9WBNXQ4P-_0
