Default OS .91HZ, Align .91H "like OS .91 SZ-H" mixture needle positions.

Ok all I really have to go off of is the internet. At 2.5 turns high and low it seems rich and this is the break in if I am reading the manual right. At 2 turns out and the mid needle closed all the way or at 2 turns like the high needle it gets hot quick but seems to run great.

Where am I supposed to be? Do these things just run a bit hotter? Uncomfortable on the back plate in 4 or 5 seconds at 1 minute of 1872 HS. I shut it down I need to figure out what's up.

There is no way to tell you what your needle settings should be. I don't think there are any 2 motors that have the same settings.

You simply have to go by sound and feel.

My needles are at 1 1/2 on the high and 1 1/4 on the low. I am running 1980 on the head and motor is around 205 degrees.

There are many variables such altitude, atmospheric conditions, fuel, pipe etc...

I know I just wanted to hear other settings so I can understand how people are using the high and mid or mid at all. Cool thanks

Hi, my hz seems to be making good power, but i am a bit lost, as to what range, each needle covers.
does the mid range go from 1/4 to 3/4 ? and where does the top end start kicking in?????
thank you Derek
