Grass trimmer full-throttle tuning?

[John Doe]

Removing the plastic plug so that the high-speed jet can be adjusted.

Good idea, bad idea, no big deal?

Thanks.

[Steve Barker]

it's the only way to really get it right.

John,

Don't understand your question. If the carb needs tuning then you (or someone) will need to remove these plugs to tune it. There are lots of ways to deal with these caps. If the carb doesn't need tuning then don't mess with it.
