rebuilding the carbs question

[mabryant]

I just got my carb kits in today from I-boats. Tomorrow I will be removing both carbs and taking a part and taking pics or videos of the dismantle
so I don't forget anything. So what I wanna know should i soak the carbs or just break them down and use carb cleaner spray and a air hose ?
If I soak them is over night long enough or does it really need that long ? I was told they were rebuilt 2 years ago. They look pretty good
I haven't seen any varnish coloring in the bowls. I'm hoping this will stop the leaking fuel in carb #2. I'll also be rebuilding the fuel pump as soon as
that kit comes in. I sure hope I can do this cuz a local guy wanted $425 to rebuild them both.

Thanks

If you already have them off the motor, AND you have the soaking container and fluid, then soak them overnight. Blow them out with compressed air and reinstall. All of that assumes you have dismantled the various jets and needle valves. They should be soaked together.

If not dismantle them. Spray them paying attention to each orifice,. Blow them out with compressed air, let them dry and then re install the jets, etc. A new bowl gasket should solve your leaking problem, unless you have a crack in the bowl or carb body. OR, unless there is a sticking needle valve.

Don't soak ANYTHING that has rubber or plastic.
The needle might have a rubber tip??
The seat might have a rubber seal in it??A solid needle means rubber in the seat.

​The soaks can melt the plastic or rubber making it useless.

​The top of the carb is a welch plug. It needs to be removed and the passage cleaned.
The kit should have a new plug?? if not then don't remove the old.

If you don't know how to reinstall the plug, ask.

​Unless the carbs been stored upside down and full of crud??
It should be fairly easy to clean with a can of carb spray.

I use Dawn soap and water then rinse with fresh water and blow dry.
​Don't use WD or any sprays as the fuel will just wash it away and possibly make it harder to start.

One thing I do when I rebuild, or merely cleaning, any carb. And that is I take one strand of wire from a typical stranded wire and use that to feed through the little passages to make certain they are cleaned out and flowing correctly. And since the wire is copper, it doesn't harm anything.

I did fight a carb problem years ago with a very small passage way in a Suzuki carb on my ATV that I never seen because it was in the lower part of the carb bowl. It would not start when cold because of a plugged tiny passage way in the fuel bowl that wouldn't allow fuel into the choke tube. And I cleaned that carb three times with carb cleaner and compressed air before figuring out I need to run a small wire through that passage to verify it was open. It wasn't opened and after clearing that one little passage, the carb worked perfectly after that.

So make sure you go slowly and cover everything. JMHO

They have this amazing tool called a "tip cleaner"
​It's an assortment of tiny wires that are all in 1 case.
Each wire has an abrasive spot to help clean the passages.
Just like opening a pocket knife.
​Cheap too.
