Re: Are the yamaha two strokes always hard starting
This is a 25" carbed model...it also has that choke on the front. I'll have to check again if i can remember when i get home from work to get the actual part number. I've added some additives and i'm putting a yamaha fuel/water separator on this week....it still seems it likes to crank and crank then when it finally sputters it's really weak. i'll crank a few more times and all of a sudden its like the fuel catches and starts right up. I've tried all different ways of starting and it pretty much does the same thing. This always happens when the boat is left sitting for a week. after starting the first time everything's fine...it's just like it's not keeping enough fuel to start until you crank it forever. is there a check valve or anything to keep the fuel inside the engine after shutdown. i deal with fuel controls on jets and they have a valve that will shutoff so that fuel doesn't get out of the control so that it will be primed and ready to start the next time.
My starting procedure is priming the ball (arrow up) until it starts getting firm, then i advance the throttle slightly, push in on the key and turn. I've also tried not priming the ball and then doing the above, i've also primed the ball and not pushed in on the key and i've also primed, pushed key in, and not advance the throttle to start.
Will adding a water separator affect this in any way? i don't want to make a starting problem worse
