    1200 non powervalve loosing prime??

    Its a boat with 2 1200 non powervalve engines in it. One of the engines will not start unless you cover the carbs with your hand to choke it. turning it over with the choke won't do anything you have to force it to suck fuel. I'm going to pull the carbs, and make sure the needles aren't sticking, and the fuel pumps are in good condition, but what else should I look at?
    I don't thinkg its the needles, because you can see there is no fuel flowing through the filter until it starts. After it starts it runs fine.

    Any suggestions??


    Thanks for the help.

    You could install a primer kit, but it sounds like those carbs could use a good rebuild. How many hours and what year is it?

    its a 98. I'm not sure how many hours. The carbs have probably never been rebuilt if i had to guess. I've just never seen one do this. Usually they will start and run bad if there is a fuel pump problem. This one won't start, but runs great once it is running.

    Hopefully some of the check valves are brittle and cracking. if I open them up and everything is in great shape, I'm not sure where else to look.


    Thanks
