Carb rebuild

[izuizme]

Merc 500-50hp I ordered 2 repair kits for this motor it comes with a new welch plug & body channel plugs . I have no idea how to remove these parts. Seems like they need to be drilled out. Can I get by without doing so?? Also the idle tube (brass screw) is frozen, must it comeout and be replaced ?? Its also in the repair parts kit.?? CONFUSED...

Re: Carb rebuild

These welch plugs are caps covering the actual screw slots and such. They can be pryed-out like a freeze plug. HOWEVER, if you can blow compressed air thru the associated passages, or better yet, get carb cleaner to spray thru them, do not remove them ,as there is no need.<br />They are set-and-forget,non-adjustable or adjust once, anyhow, and if it aint broke........<br />One caveat trho, don't soak these carbs in carbonic carb cleaner (the stuff in the one gallon can). It eats the seats and anything non-metal.
