I took the carbs off my boat yesterday, and stripped them down tonight. At least, I went as far as I could.

In the rebuild package I ordered, there are round lead pluks, about 1/2" in diameter, as well as lots of o-rings, and plastic bits.

On the main body of each carb, you can clearly see the place where these lead plugs go, and that they would easily pry out. The problem is that the book make no mention of them at all. I have no idea what is underneath them, or what they are for.

Has any one done this before?

Oh, yes, I also stripped the head off one of the small orifice insterts. It is fine otherwise. I can tighten it, just not loosen it. Can I just leave it in there?

Thanks, Larry

you are kind of going to town. those plugs are boil out plugs and unless you have the right tool to re-install the new ones you should leave them alone. you probably did not use the right screwdriver on one of the jets and thats why you striped it. if there are no obstructions to the jet (bits from stripping it hanging over the orifice) just leave it alone. get yourself some "power tune". mercury makes it. spray through every hole, nook and cranny. rinse with a stream of water from a garden hose nozzle. shake the majority of the water out and set the main body out to dry. if you have compressed air you can blow it out. put the rest of it back together the way it came apart. just check the float level. it should be right on if you did`nt mess with it. alot of folks tend to overwork a carb rebuild. adjust it as per manufacturers instructions, good luck, steve out.

Thanks Steve. I thought I might be going too far, but I kept looking at the parts in the rebuild kit, and then at the carbs, and knew they could come apart further. I guess I always go a little to far...

Thanks much, Larry
