    My boat wont start when it is cold, but if you manually choke it it will start fine what could be causing this?

    It's helpful to know if you have an I/O or an outboard, and the motor manufacturer. Off my head, I would just think the fuel is disappearing from the carb bowl until you apply the manual choke. But that is just a real wild a.. guess.

    It's a 32 year old 2 stroke:wink: Could be several things, but I've always had to choke mine ('80 75hp 'rude) to start it when it's cold, that's why the choke is there. And then let it warm up awhile, even after I rebuilt the powerhead and carbs. Could be a lot of things (dirty carbs, fuel line leaks, etc) but if it runs and starts fine once it warms up I'd chalk it up to just being cold. I've sometimes thought that OMC stands for "Operator Must Cuss" when I'm starting mine on cold mornings:smile2:

    jason ,if im reading your post correctly,you are saying your electric choke isn't working.if that is the case,take your motor cover off and check to see if the linkage has come apart,and some times you have to lubricate the small hole that the choke cylinder goes up and down in,another problem may be the toggle switch that opperates the choke ,hope this helps. larry d. grady

    I have to take the cover off, and work the choke to get it to start. I've done some studying, and it appears to be missing the rod that runs from the elitric choke selenoid to the carb. Does anyone know where I could find a diagram of the carbs.
