Hipa Carburetor Replacement Kit for Echo PB-250 PB-250LN ES-250 – RB-K106 Direct Fit, Includes Gaskets & Spark Plug

Hipa PB-250LN Carburetor Replacement Kit is a complete drop-in replacement for Echo PB-250 (RB-K106) blowers, supplying the carburetor and all small parts needed to get your blower running again.

If your Echo PB-250 or ES-250 leaf blower is bogging, won't idle, or refuses to start, a worn or damaged carburetor is a common cause. The Hipa PB-250LN kit replaces the OEM RB-K106 assembly and includes gaskets, primer bulb, tube assembly, cleaner, and a spark plug—everything to restore fuel delivery and ignition without an extra parts run. Note that some PB-250 models use a different carburetor (WTA-33), so confirm your model’s part number before ordering to avoid mismatch.

Which models and part numbers does this kit replace?

The kit is engineered to fit Echo PB-250 and PB-250LN ES-250 blowers that originally shipped with the RB-K106 carburetor. It is compatible with the factory part numbers listed below, offering a direct replacement without modification.

• Direct fit for Echo PB-250 and PB-250LN ES-250 using RB-K106
• Replaces OEM numbers RB-K106, A021003660, A021003661
• Not compatible with models using the WTA-33 carburetor—verify before purchase

What parts are included and what will you need to finish installation?

The Hipa kit ships as a ready-to-install set so you won’t need to track down small consumables. It contains the carburetor and every common gasket and fitting you’d normally replace during a rebuild, plus a new spark plug to ensure reliable starting after service.

• 1 carburetor body pre-assembled for PB-250 RB-K106
• 2 gaskets to seal the intake and mounting surfaces
• 1 primer bulb and fuel tube assembly for proper fuel flow
• 1 small cleaner packet and 1 spark plug to complete tune-up

How difficult is installation and what should I check first?

Installation is straightforward for anyone comfortable with small-engine maintenance: remove the air filter and housing, detach fuel and throttle linkages, swap the old carburetor for the new one, then reattach lines. Before you start, verify the engine model and carburetor part number, work in a ventilated area, and drain or contain fuel to avoid spills.

• Confirm your blower uses RB-K106; do not install if your carburetor is WTA-33
• Have basic hand tools: screwdrivers, pliers, and a socket set
• Check for cracked fuel lines and replace if necessary when installing

What performance changes can I expect after replacing the carburetor?

Installing a new carburetor generally restores consistent idling, smoother throttle response, and easier starting when the root cause was fuel metering or a failed primer. While every engine’s condition differs, this kit removes a common mechanical failure point and supplies fresh seals and a primer bulb to improve fuel delivery.

• Better cold starts thanks to a new primer bulb and clean fuel passages
• Smoother idling and reduced stalling under load
• Reduced fuel leaks due to new gaskets and fittings

Who is this for: The Hipa PB-250LN Carburetor Replacement Kit is intended for DIY mechanics, landscapers, and homeowners who own an Echo PB-250 or PB-250LN ES-250 equipped with the RB-K106 carburetor. It suits anyone wanting a complete parts bundle that replaces worn components and gets a blower back to reliable operation without sourcing multiple small parts. Remember to confirm your blower’s carburetor part number before ordering to ensure compatibility and avoid returns.
