carburator problem

[beachcomber]

I have a 140 HP Evinrude (early 90s?). It accelerates and slows down spontaneously while running. I am told this is due to corrosion in the linkage between carburator and throttle, and can be corrected by replacing some parts. Are these available as a kit from the manufacturer and should any Evirude dealer have them? Thanks.

Welcome to the forum,BC. <br />Does it loose boat speed when it revs up, or gain speed when it revs?

It looses speed when it's just under way,and sometimes it gains speed also by itself. As I said, I was told by an experienced boater that this is due to corrosion in the linkage between the carb and the throttle; I am trying to find out if the manufacturer supplies a kit of replacement parts to correct the problem.

just a thought is all the conections tight?

Re: carburator problem

sounds more like a cylinder cutting out....a linkage problem would be less prone to cause cutting in and out.......I'd be looking to ignition.......<br /><br />my meager opinion
