Echo SRM-2620 Parts and Fitment

The air filter's cover piece (A226002040) is sold separately on some listings and bundled on others - if a tune-up kit looks incomplete, check whether the cover was supposed to come with it before assuming a part is missing.

The SRM-210 splits from the SRM-225 on exactly one part - the carburettor. The SRM-2620 is a bigger break: the carburettor, the air filter, the spark plug and the fuel line kit are all different numbers from the 21.2cc SRM-225/210 range. A tune-up kit bought for "an Echo trimmer" by engine size rather than by number will not fit a 2620, because none of the four consumable parts cross over.

The one exception is the gear head at the bottom of the shaft - P021008182 is genuinely the same assembly across the SRM-225, SRM-225i, SRM-210 and the 2620/3020 pair, covered in full on the Echo gear head and gearbox page. Everything else, match the number, not the badge - the same rule the carburettor page and spark plug page cover for the rest of the range.

Echo's own listings group the SRM-2620, SRM-2620T and SRM-3020 under one parts platform. The carburettor (A021004600/A021004601), air filter (A226002030), spark plug (A425000060) and fuel line kit (90182Y) show up on genuine and compatible listings for all three badges without a separate number for the 3020 - order by the part number here regardless of which of the three is stamped on your shroud.

The same engine also sits under the PAS-2620 attachment power head, so a PAS-2620 owner works from this same parts list rather than the fixed-shaft SRM numbers above - the coupler and attachment side of that system is covered on the PAS attachment parts page.

The SRM-2620 is built to run .105 in line all day without bogging - the commercial-class step up from the .095 in that the 21.2cc homeowner trimmers are sized for. The Speed-Feed 400 head (99944200907) is confirmed to fit the 2620/2620T alongside the SRM-225, so the no-rewind upgrade covered on the trimmer head page applies here too. The full diameter-by-model breakdown, including why stepping a smaller trimmer up to .105 in bogs the engine, is on the trimmer line size chart.

A 2620 that turns rough or whines under load rather than just cutting badly usually points at the gear head (P021008182) rather than the line or the head itself - that is the one part this machine shares with the smaller range, and it bolts on as a complete assembly with no rebuild kit. If the machine will not start at all, work through fuel, filter, spark and carburettor in that order on the won't-start page before assuming the worst.
