Help with Intermittent engine bogg.........

[mrcj001]

1976 Evinrude 70HP

Last two times out, I am getting a Intermittent bog.

Runs good when first take out for the day.....after fishing a while then I go to move...the engine wont take throttle past idle speed.

Then sometimes it runs normally.

I wouldn't swear....but I think when I tilt the engine forward....it starts running fine again.. sometimes yes....sometimes no.

If it is in fact working better with the engine tilted, I would check the float settings in the carbs.

I rebuilt the carbs last summer. I checked the float settings Before and After the rebuild and never had a problem until the last two times out.

Is bogging caused by too much fuel or not enough?

I`m guessing a "sticky float".........

With engine off try squeezing the primer with some firm pressure, if it dosent hold that pressure suspect leaking floats.
