Thanks Hermee
I bought mine off ebay from an Aussie seller - $13. Its just I hate giving China money directly, at least with an Aussie seller, some money goes to the govt by taxes. Although in thinking how much interest they probably pay to China in loans, I should have just saved the $6 haha. Anyway, took 1 week v 1 month.
ENGRISH manual is right - it lists as follows : 01 - 2 stroke 1 cyl, 02 1 stroke Per cyl, etc.
As soon as I saw it say the Ryobi was idling at 1050 rpm (mentally calculated 2100 rpm as the correct idle and changed the setting)
Thinking about it, I may have had it set on 02 for the Briggs as well, not sure.
Got the trimmer up to 20 something thousand on setting 3, so that was ruled out.
I tried another trimmer (homelite with different engine) and got about the same, bit faster idle (no clutch) and same top speed (roughly about 200 rpm more) The engines on both are perfect inside, and good plugs on both.
Checked my generator 1/2 hour ago - 3000 rpm on setting 2 - exactly what it should be without load.
I think you are right - 12,000 does seem pretty high. It also says the head spins at 9000 rpm - that is definitely faster than I think they run.
By the way, I use Caltex 98 RON and the machines seem to have better throttle response and starting. I reckon running high octane doesnt have any downsides (unless you use engines in 50 degree heat). Many trimmer manuals actually specify 98 octane (disguised as 91 octane in the AKI scale).
Thanks again
