David Kitchen from Rayong in Thailand is having jetting issues with his grass strimmer. He asked what the corerct procedure was for chopping and came up with this:

No joke, my strimmer has a jetting issue. Now how do you do a plug chop on that. Do I cut long grass really quickly and then hit the kill switch. The last bit was a joke after all.

Well, I don't have any other better suggestions so I think he's got the answer

Anyone else know how to fine tune a strimmer?
