Carb Float Adjustment

[ewaltb]

Took off the carbs on my '91 120 Force to replace all gaskets. Put the gaskets on but never adjusted the floats. <br />My engine will not stay idling in the water. It runs for a few seconds then shuts off. After a cranks it won't start again. Could it be the floats? The bottom carb is leaking a lot of fuel.

Check the float valve. Probably stuck open.<br /><br />/Bear

I forgot: Do not adjust the float level if there isn't a obvious reason to do so. <br /><br />/Bear

Re: Carb Float Adjustment

Hey Bear thanks for the info. I will definitely make sure it isn't stuck open. Why do you think it isn't a goodto adjust the float? I have the manual and it seems like a relatively straight forward process.

Re: Carb Float Adjustment

If you have the manual it's a different story. Check the level and adjust if necessary. <br /><br />I tried to say that float levels don't change just like that. I there is something wrong with the carb don't start to adjust every jet, screw or lever - deal with the actual problem. In general that is. Since you have the manual and know what you are doing... Didn't know the whole story. Sorry. <br /><br />Sure hope the float level is right and there is no need for adjustment. Then I still look good. <br /><br />/Bear

Re: Carb Float Adjustment

Thanks again. Yeah when I pulled the carb the first time I jolted the carb around and just thought "oh well". But I assume that I smacked to many things around inside. It will most likely need a rebuild this weekend. Thanks for the advice. These are the things I need to hear before I start ripping things apart.

Re: Carb Float Adjustment

Sorry to put this question on someone elses thread, but if my 200hp merc stalls in very low idle, but is fine in neutral, and only after a few hours of running, should i look into my carbs as well?? How hard is it to check for something abnormal? I have never tore down a carb before but i do have the manuel.
