It sounds like the carb's just not set up correctly. It's easy to miss the settings. See the note we posted earlier about getting the SuperTigre carbs set up. The instructions apply to all SuperTigre carbs.

Another problem with the large SuperTigre engines is the fact that it's easy to get them flooded while trying to start them. I tend to flood them if I've not run one in a while. Choke carefully. You can usually tell the engine's flooded when it will on "pop" occasionally, and will tend to run backwards when propped.

In many cases, we use our safety stick and prop the engine backwards to get it to start running. Once it's running, we then get the engine leaned to proper RPM.

We usually use an O.S. #8 plug and 5%-10% fuel. The engines like lower Nitro fuels better than the higher-nitro stuff. Oil can be as low as 10%-12% on a well-broken-in engine. If the engine's not broken in, then use fuel with at least 15% oil.
