    Exclamation '93 waverunner 3 carb help

    ok thanks for visiting my thread does anyone know what kind of mikuni carb is on a 93 waverunner 3 650 model had if anyone knows if a stiff/hard diaphragm pump or the fuel pump diaphragm could cause it to hard start on the first start after 1 day of sitting aound.

    Because it is hard to start on the first time ever, i have to put a little gas in it to start it then let it sit and idle because if i hit the gas it will spudder and die but if i let it sit and idle it works great.

    also a carb rebuild kit would be nice if i could locate the right one for this model thanks if you can help.

    ok I found this plug in this hole, the hole is at the very bottom of the carb it goes all the way through the carb to the throttle valve inside and i cannot find this pin or hole on the carb repair manual is this suppose to be there or did the factory mistakenly leave that there.

    it's supposed to be there.
    Diaphragms should be soft...just replaced them on a couple of skis I'm working on, made a world of difference.
    I'll ask the owner where he got the kits from, I know they were $30 some odd a piece
    I think you can get the diaphragm it's self from just look at the i.d. plate on your ski an search that should be something like WR650
