speed ranges from 9,700 to 10,300 r/min (When
using metal blade : 10,500 - 12,000 r/min). Make
sure the cutting device does not rotate when engine
is idling. When final adjustment is completed, the
engine should idle, accelerate smoothly, and attain
WOT per above specification.

on the non thread side of limiter plug tool #91020

idle and H mixture needle holes to comply with
Emission Directive.
