Carburetor Cleaning Made Easy: Clean Your Outboard Carburetor Without Removing It

How to Clean Outboard Carburetor Without Removing

Bill here, your friendly neighborhood boat enthusiast, and I’ve got a little tip for all you fellow seafarers out there.

If you want to keep your boat’s engine running like a well-oiled machine, then listen up. The key to a smooth-running engine is a well-regulated mix of fuel and air, and that’s where the carburetor comes in.

Now, I know what you’re thinking. “But Bill, cleaning the carburetor sounds like a pain in the stern!” And I hear ya, shipmates. Disassembling the carb and cleaning it piece by piece can take all day, and who’s got time for that?

Well, fear not, my salty dogs. There’s another way to clean the outboard carburetor without disassembling it. And I’m about to spill the beans on how to do it.

But first, let me just say this: if you’re anything like me, then you know that a clean carburetor is key to a smooth ride. It’s like giving your boat’s engine a spa day. And who doesn’t love a good spa day, am I right?

So, here’s what you gotta do. First, remove the air intake and spray some carburetor cleaner into the opening. Then, turn on the engine and let it idle for a bit. This will allow the cleaner to work its magic and break down any gunk or debris that’s clogging up your carburetor.

Next, rev up the engine a bit and spray some more cleaner into the carburetor. This will help to flush out any remaining debris and get your engine purring like a kitten.

An excellent way to clean an outboard carburetor without removing would be by using the Berryman B12 Carb Cleaner.

  • First, blend 4 oz of the B12 with a full gasoline tank. Use a funnel to pour the B12 carb cleaner into the tank, so the paint isn’t ruined.
  • Then, go for a slow ride, so the carb cleaner flows through the idle system. Be sure to avoid high RPM while the B12 carb cleaner is in the gas tank, as it may wash the oil off the cylinder walls.Once the RPM rises, then you know the carb cleaner is working just fine, and thus, you should turn the idle knob down.
  • To ensure the carburetor is thoroughly clean after using the B12 carb cleaner, squirt some aerosol B12 into the carb’s intake mouth through the pilot air jets. Can’t find the jets? On some carbs, they’re located beneath the big vacuum diaphragm.

Clean 2 stroke carb without removing

There are several other products on the market for cleaning a 2 stroke carb without removing, up your outboard’s gummy mess.

These include:

i. Seafoam

An excellent product in the form of a spray can that normally goes for around 10 dollars. The spray works by dissolving grime and carbon off the carb and leaves only an oily film.

In case your carb is particularly gummed up, let it soak in a lacquer thinner before applying the seafoam spray. But, be sure to use these products in an outdoor setting as the fumes are quite hazardous.

ii. PowerTune

You spray this one directly into the carb’s throat but be sure to follow the specific instructions indicated on the product.

Caution: rubber and plastic parts of the carb shouldn’t come into contact with the carb cleaner, as they might get destroyed. Cleaners that contain isopropyl alcohol are a safe option for the carb’s delicate parts.

My Useful Tips

Taking maintenance measures for your carb not only assures you of safe boating but also keeps your carb dependable for a long time.

Here are a few maintenance exercises that are associated with the proper working of the outboard carburetor. You should consider doing them after each sailing trip:

  • Flushing out the outboard – start the engine with the throttle on neutral, and the engine will do its work. Ensure the gear stays at neutral throughout the exercise.
  • Checking the water pump – while flushing out the outboard, feel the temperature of the water stream at the top of the water pump; it should be warm but not hot. In case there’s no stream, check the outflow tube to ensure debris does not block it.By inserting a wire and working the blockage, the stream should come forth as it ought to but make sure you’re inserting the wire with the engine turned off. If there’s still no stream, the water pump might be broken, and you may have to replace it.
  • Burning the fuel – disengage the fuel line and let the engine completely burn the fuel contained in the carb. When the fuel is all consumed, switch off the engine and turn off the battery.
  • After you’ve flushed the engine, remove the cowling and inspect if there are water or fuel leaks. In case there are leaks, get in touch with a professional mechanic to fix it.
  • Spraying the carb with WD 40 or another anticorrosive lube – do the same for the other moving parts.
  • Making sure the fuel you’re using is fresh.
