I have a 93 4 stroke. Stock engine with governor disconnected and carb mildly jetted. Starts right away and idles good. When I take off it runs great and will run wot then after short period it will only take half throttle. If you try giving more it wont take it. It almost seems like its running out of fuel in the bowl. I checked the fuel pump by pulling line loose will running and it seems to be pumping. It fills up a bottle does not seem to have a lot of pressure which is probably because of vacuum style pump. I even swapped fuel pump for another I had same problem. I tried hooking both up to increase volume and it ran wot longer than with one before it started back not taking much more than half throttle.
I took the pedal start off and tried a push button start switch it cranked right up but the died as soon as you let off button. Does the starter supposed to run constant when it is running?
