This is a old engine that I am putting on a plane and I no longer have the manual. Can someone tell me what the low speed and high speed needle settings are or point me to a place where I can download an owners manual? Thanks.

You can download a copy of the manual on the Ace Hobby website.

Hi!
As any other glow engine...Open the high speed needle some (2turns) and start the engine!!! Then full throttle and adjust the high speed needle by ear! Then throttle down and adjust the low speed (idle needle) by ear! Simple as that!!!

In the TT Pro instruction book it states to close the high needle valve and then open it about 2 - 2 1/2 turns as a good place to start.
It does not give a starting setting for the low needle.

Thanks all.
