my gas powered rc car wont start i started it like 4 months ago but it wont start now i dont know what to do?

Try priming the carburetor by putting or pumping a little fuel in to it so that combustion can occur when you start it. Use very little fuel and stand a few feet away when you try to start it.

Did the battery die? Try jumpstarting it. Most cars will not start after sitting for long periods of time…and 4 months is a long time.

You may need to clean the carburater as well.If so feel free to buy regular carburater cleaner for a car,Then spray it thouroughly.Be sure it is totaly clean and dry before you put it back together.
