Gas Mixture for an old Weedeater

FL25C Pull Cord

From: V. G.

Inhereted a older feather lite Weedeater (probably from the late 80`s early 90`s) still in good shape. Used very little. The engine tag says 18cc. Couldn`t find a model number. I was wondering what size string & gas mixture to use? 87 octane OK? Also looks like only one feed from the spool to the one exit hole to the hub on this one. Thanks in advance.

Hi,
it’s hard to determine model number, all newer models use 20cc or higher. The usual gas mixture is 1:50. The string depends on lawn your are using trimmer on, read more about it here. Perhaps it’s better to use thinner line for 18cc trimmer.
