HI folks,
I purchased a old but in great condition supertiger 2000. Can someone tell me what is the best fuel/ fuel mixture for this big moter?

Depending upon how much the engine's been run, the fuel requirements can differ.

If it's never been run, or you have absolutely no idea how it's been run, use at least two gallons of fuel that contains AT LEAST 15% oil content. All-castor was preferred by SuperTigre at the time the engine came out. After that, you can go to a fuel with 10%-12% oil content, also all-castor.

Nitro up to 10% is OK, but 5% seems to run the best.

For glow plugs, people have had success with a variety. An O.S. Max #8 plug or #A3 plug seem to work well, but many people have also used the O.S> Max Typer F plug with great success, especially if they're using 0% nitro fuel.

Prop the engine so that it turns in the mid- to high-7,000's at full throttle on the ground when leaned to just rich of peak. You'll find the engine is very, very reliable.

Hi,
Thanks for that info. The motor is mounted on a 1/4 scale Byron Husky and it seems that the plane has been flown some. I tried starting the engine yesterday with 10 nitro and 16% sytetic oil. The engine would run , but would cut out often. Can I still buy fuel with castro, or can I add my own ? The prop size on the plane is 18x6.
thanks,
Frank

The easy answer is that SIG sells excellent all castor fuel in 20 and 25%, and 0, 5, and 10% nitro.
