New-to-me Echo GT2000R trimmer: questions
Hi there: I just picked up one of these for $50, from a golf course that was replacing their "fleet" with straight-shaft trimmers. I assume heavy use but also reasonably careful maintenance; it seems to start and run fine. I know the plug and filters are new, and the other basic stuff too; there's no guard, though. A couple of questions:
1. It currently has strings (I think .105 or something) with a metal core in them, but the fellow said I'd have a hard time finding that. What's the most sensible replacement line for my pretty basic needs (yard/garden grass trimming, no fence-posts or heavy weeds or anything like that)? Would going to a smaller diameter mean the head will have a harder time gripping the lines or does that mechanism adjust to different sizes OK?
2. I heard from the local sales rep to use 89 octane gas or higher unless I want to mix a new batch every month. Is that true?
3. Any other suggestions for care and feeding?
