Nothing wrong with starting nitro. However, the LHS guy wasn't lying about the frustration. Nitro isn't as easy as plug-and-go electric. You will need to have some patience, especially when breaking-in the engine and adjusting the carb. Nitros are easier than ever to own. Most manufacturers have excellent manuals with their RTR nitro cars. If you follow the instructions and take the time, you will minimalize your frustration.
