Echo SRM-210 Parts and Fitment

The air filter also sells as 13031054130 and A226000472, and cross-references to Oregon 30-119 and Stens 102-565 - four numbers, one filter. That is normal for Echo consumables and worth knowing before you decide a listing is the wrong part.

Engine-side, the SRM-210 and SRM-225 are close relatives: the air filter is the same A226001410, the primer bulb is the same 12538108660 / 12538146730, and the Speed-Feed 400 head fits both. That is why a generic "225 tune-up kit" usually works on a 210 as well.

The carburettor is the exception, and it is the part most often bought wrong. A carburettor sold for the SRM-225 lists GT-225, PAS-225, PE-225 and SHC-225 - a different Zama unit. The SRM-210's carburettor groups with the SRM-230, GT-200, HC-150 and PE-200 instead. The two look similar in a photo and are not interchangeable. Match the machine names on the listing to yours, not the engine size.

The full logic of when a gummed carburettor needs replacing at all is on the carburettor page.

The SRM-210 runs a 21.2 cc two-stroke and takes a 50:1 fuel mix - the same ratio as every other Echo handheld, so one can of 50:1 two-stroke oil covers the whole shed. Running it richer or leaner is a common cause of a 210 that will not idle cleanly.

The parts that fail on a 210 are rarely the ones that wear - they are the ones that perish. Fuel lines go hard and split where they enter the tank, and the primer bulb cracks. A 210 that will not prime is far more often this than a carburettor fault. The repower fuel line kit (90097 / 90069) bundles the lines, and tune-up kits add the filter and primer bulb in one purchase.

If the machine turns over but will not catch, work through why an Echo will not start in order - fuel, filter, spark, then carburettor - before spending anything.

The SRM-210 is a .095 in machine. It ships with a bump head and takes twisted line 330095071 comfortably; the Speed-Feed 400 (99944200907) is the common upgrade and fits the SRM series, the 210 included. Whether a given head can run heavier .105 in line depends on the head, not the badge - the diameter chart across the range is on the trimmer line size page.

For the wider parts picture - which numbers cross to which machines and which are worth stocking before the season - the SRM-225 parts page covers the family the 210 belongs to.
