C3-EL43C Carburetor Tune-Up Kit

Key Features

  • Complete All-in-One Maintenance Solution: Includes a precision-calibrated carburetor, high-efficiency air filter, fuel line, fuel filter, and spark plug, providing everything needed for a full engine refresh in one package.
  • Optimized Fuel-Air Mixing: The C3-EL43C carburetor is engineered to deliver a precise fuel mixture, ensuring the high-torque performance required for heavy-duty concrete and masonry cutting.
  • Enhanced Filtration Protection: Features a high-capacity pleated air filter (578243401) designed to trap ultra-fine concrete dust and debris, significantly extending the life of the engine's cylinder and piston.
  • Ethanol-Resistant Components: The fuel lines and internal carburetor gaskets are manufactured from high-grade polymers that resist swelling and cracking when exposed to modern ethanol-blended fuels.
  • Reliable Ignition Spark: Includes a premium-grade spark plug with a heat range specifically matched for the high-operating temperatures of Husqvarna cutoff saws, ensuring consistent starts and smooth idling.

Replaces / Cross-Reference Part Numbers

  • Carburetor: 510 18 12-02, 510181202, Zama C3-EL43C, C3-EL53.
  • Air Filter: 578 24 34-01, 578243401, 544 18 16-02, 544181602.
  • Spark Plug: NGK BPMR7A, Champion RCJ6Y.

Compatibility & Fitment

This tune-up kit is specifically designed for Husqvarna’s professional-grade power cutters produced after 2013. Key compatible models include:

  • Husqvarna K750: Fits 2013 and newer models (verify the carburetor style).
  • Husqvarna K760: Direct fit for the standard K760 and K760 II models.
  • Husqvarna K770: Compatible with the newest generation K770 cutoff saws.
  • Zama Platforms: Replaces Zama C3-EL43C and C3-EL53 series carburetors.
  • Note: Please ensure your saw utilizes the external primer bulb system and the pleated square air filter before ordering, as older legacy models may use a foam-only filter system.

When to Replace

  • Saw Won't Start or Hard Starting: The most common symptom; internal carburetor passages are clogged with dust or "varnished" fuel from the previous season.
  • Engine "Bogs Down" Under Load: The saw runs at idle but loses power or dies as soon as the blade hits the concrete, indicating a restricted high-speed fuel circuit.
  • Erratic Idle (Surging): The engine speed fluctuates or "hunts" at idle, often caused by an air leak in the fuel line or a dirty low-speed jet.
  • Visible Fuel Leaks: Gasoline is dripping from the air filter housing or the fuel lines have become brittle and cracked due to age.
  • Poor Fuel Economy/Black Smoke: The carburetor is running too "rich," wasting fuel and quickly fouling the spark plug with carbon deposits.

Installation Tips

  • Safety First: Ensure the saw is completely cool. CRITICAL: Work in a well-ventilated area and drain all remaining fuel from the tank before disconnecting any lines.
  • Dust Control: PRO TIP: Before removing the old carburetor, use compressed air to blow off the concrete dust from the exterior of the saw. You do not want dust entering the intake manifold during the swap.
  • Line Routing: Take a photo of the fuel and pulse line routing before removal. If the "In" and "Return" lines are swapped, the primer bulb will not function and the saw will not start.
  • Filter Pre-Check: Ensure the new air filter is seated perfectly in the housing. Even a small gap will allow concrete dust to bypass the filter and cause catastrophic engine failure within minutes.
  • Fine-Tuning: Most carburetors come pre-set. However, if the saw hesitates on acceleration, you may need a specialized splined tool to adjust the "H" (High) and "L" (Low) needles by 1/8th turn to match your local altitude and fuel type.

Picky dog approved!
Color: S6-muti-color, Color: S6-muti-color
I have wasted so much money on dog balls that they won't even pick up! They finally were obsessed with the Kong rubber green/blue or red/blue ones, but they're $3+. each, and they break from the dogs squishing it. I honestly had zero expectations on these, and they BOTH picked them up on the first throw! That's huge!! Seem to work fine in the ChuckIt. As for the squeaker, at first I was like "Oh nooooo." when they both loudly started! Much to my (and my neighbors') happiness, the squeakers stopped working after a couple minutes. 🤣

The balls are great for chewers. The squeaky didn’t last long but they are perfect for the ball launcher.

The squeeker isn't durable, but the balls themselves are.
Color: S6-muti-color, Color: S6-muti-color
I have two 70+lb, ball obsessed dogs (a field bred Golden Retriever, and an Old Time Scotch Collie), and these balls are living up to the abuse they're receiving. In the fall we always lose a ball or two in the yard due to getting lost in leaves or longer grass, so I always try and buy a multi pack at the start of the season, so went with these this year. I'm glad I did. Great price for a 6 pack, they fit the medium Chuck-It launcher (a little loosely, but they throw just fine), have great bounce, they FLOAT (which means I didn't lose any at the beach), and they're super durable to the dreaded "mouth squish." The squeaker dies pretty quick, like, within a day, but it isn't the kind that can fall out or choke your dog, so no worries there. The boys are happy, I'm happy, my wallet is happy - I've already ordered another pack.
