Kit contents and fitment

This kit bundles a carburettor, air filter and spark plug for two-stroke petrol engines. It replaces OEM part numbers A03003, A07139 and A04445A and matches Walbro carburettor references WT-220 and WT-318. The package suits Homelite string trimmers and brushcutters including the ST145, ST155, ST175, ST185BC, ST275 and ST285BC model series.

When to fit this kit

Install the kit when the original carburettor floods, leans out or the air filter has collapsed from age and debris. It restores the factory fuel-air mixture on units that have run on stale fuel or ingested dust through a torn filter. The jump is worth it when compression is still strong but starting and idle quality have deteriorated.

Capacity and limits

The components handle the displacement range covered by the listed Homelite and GST models up to the 385 series. They do not fit four-stroke engines or larger commercial saws that require a different bore and venturi size. Buyers needing a complete engine overhaul or a different carburettor circuit for altitude compensation will need additional parts not included here.
