RE: How Long Nitro Engines last ?
If you have richened the engine and it still stalls and wont start when getting warm then its shot, engine life goes by how it has been run, if its been run hot and lean it wont last very long at all, if you run it a little rich and keep the temps to around 220 to 250 it can last a very long time, i have car engines that are over 20 years old with many gallons thru them and they still run fine. The sh is a good engine, well built and will last a long time if its properly taken care of, a clean and well oiled air filter will also keep you engine running a long time.
