so i noticed my ski is being annyoing lately. if i have a full gas tank when going at top speed with throtle held all the way wont bog but when the tank is 1/4 and im going at top speed it then just boggs. if i decrease the throtle a bit and then go full again it will jump but keeps bogging. sometimes when im trying to start it it also doesnt click right away unless i play with the throtle it seems to bog as well.

not sure what this could be. only thinking it might be that its not getting enough gas when its at 1/4 of a tank.
