Idle Speed Won't Adjust
Need some help. Idle is running low - around 500 rpm. Ran a jumper between B and C of the test port to adjust it; idle runs around 800 rpm with the jumper. Remove the jumper - back to 500.
If I play with the idle valve adjustment to bring the idle up without the jumper, as it's approaching 750 it starts to whistle; assuming that's not preferred.
Thanks!
