Good day, I was on a limited budget, and decided to buy a cheap 6 hp Hangkai motor from China for my 14 foot inflatable kaboat. Immediately I noticed, that I wasn't getting the speed I was expecting (about 10 to 12 mph.) I was doing about 5 mph instead. I have been troubleshooting this problem for months, and I know it is capable of more power, because a couple outings I had a nice burst of speed for a while until I turned off the motor for a bit, went on a plane. Now, I have no idea why this speed happened. Here is what I have tried; took apart the carb multiple times and sprayed with carb cleaner, checked float, checked needle valves, checked fuel lines, replaced spark plug, played around with the mixture screw to no success, and checked fuel pump. I measured the rpms, and maxes out at 3400 when it should do 5500, which is can idle at. When the motor is in a test can, the motor seems to go in and out of of a lot of rpms, even seems like it becomes more powerful when the cover is off. But it seems to go back to the same old 3400 or lower when the motor is under load on my boat. I am at a loss here, and no mechanic wants to look at my motor because it is an off-brand. Any help would be appreciated, thank you.
