Hipa SRM 225 Carburetor Kit for Echo SRM225/PAS225 – Complete Tune-Up Kit with Filters & Spark Plug

The Hipa SRM 225 Carburetor Kit is a complete, factory-tuned replacement carburetor bundle engineered to restore reliable starting and steady engine performance for Echo SRM225/PAS225/GT225 series trimmers and attachments.

If your Echo-powered trimmer, edger, hedge trimmer or power pruner runs rough, won’t idle, or is hard to start, a worn or damaged carburetor is a common cause. This Hipa kit supplies a ready-to-install carburetor that replaces Zama RB-K93 and Echo part numbers A021001690, A021001691, and A021001692, plus a full set of tune-up components so you can swap parts quickly and minimize downtime.

Will this carburetor fit my Echo SRM225 or PAS225 tool?

The Hipa carburetor is designed specifically for many Echo 225-series machines. It matches the mounting, bore and fuel line dimensions used on SRM-225, SRM225i, PAS-225 power attachments and several GT/SHC series models, but always confirm part numbers before ordering.

• Replaces Zama RB-K93 and Echo A021001690/A021001691/A021001692
• Compatible with SRM-225, SRM225i, SRM225SB, GT225 and related models
• Also fits PAS-225 power attachments, edgers (PE225) and hedge/pruner variants
• Verify your engine model and existing part number for a precise match

What’s included and why is this an "all-in-one" kit?

This kit bundles the carburetor with the common wear items needed for a tune-up, so you won’t have to source multiple parts. Everything arrives pre-assembled and factory balanced so you can replace the carburetor and refresh associated components in one service session.

• Hipa 225 carburetor (factory tuned)
• Two air filters, one spark plug, two primer bulbs
• Gaskets, fuel filter, fuel tubes, grommet and vent included
• Designed to save time and reduce separate part purchases

How does the Hipa carburetor affect engine reliability and performance?

The unit is wet-flow tested to emulate real operating conditions, which helps ensure consistent fuel delivery and smoother running out of the box. Durable materials—brass fittings, composite rubber diaphragms, and an anodized aluminum body—resist corrosion, heat, and wear for longer service life compared with cheaper cast components.

• Wet-flow tested to check fuel metering under load
• Brass components for durability and corrosion resistance
• Anodized aluminum body reduces wear and heat damage
• Composite diaphragms maintain sealing and responsiveness

What are the key dimensions and connection sizes I should check?

To ensure a correct fit, compare your machine’s mounting and bore dimensions to the carburetor specs. Hipa provides specific measurements for mounting hole spacing, fuel inlet/outlet, and bore diameters to match the factory layout of Echo 225-series engines.

• Mounting hole center-to-center: 31 mm
• Throttle bore diameter: 9 mm, venturi: 9.15 mm
• Choke bore diameter: 11 mm
• Fuel inlet: 4.6 mm, fuel return: 4.0 mm

Who is this for: The Hipa SRM 225 Carburetor Kit is aimed at homeowners, landscapers, and small-engine repair shops servicing Echo 225-series trimmers, edgers, hedge trimmers, and power pruners. It’s particularly useful for anyone who prefers a single, ready-to-install replacement plus the common tune-up parts needed to get a machine back into reliable, daily use without sourcing multiple components separately.
