Hello all,

I have a few questions on engine settings from a newbie.

First of all, I bought a Thunder Tiger .46 Pro about 6 years ago and can't find the manual. If someone can send me a pdf or point me in the direction of a pdf of it on line, I'd really appreciated it.

Secondly (and sadly), I'm just breaking in this engine and I am trying to understand the needle settings on the carburetor. I know there is a low end and a high end, but I'm not sure what each one does, or where to set each one. I did get the engine running and realized that the carburetor was set too lean because the engine would stall at higher RPMs. I opened the high end needle up until I could just run the engine at the higher RPMs. I let the engine run for 5 minutes, and will do so a few more times to break it in.

Is this where I want the carburetor needles set for break-in? And once the engine is broken in, do I want to open the carburetor up a little bit more to run a little more rich for better cooling? I'm not sure why there are two needles (high and low), instead of just one. Isn't it just the gap between them that determines how the engine runs?

Finally, does anyone know the default needle settings for the Thunder Tiger .46 Pro?

Thanks for any help/advice you can offer.
