Help me identify the make and model of my free rc car

[Cocolee]

A friend gave me a free nitro rc that need some parts to make it run but he doesn't know the make or model. Can anyone help identify what I have. Need to know the type of engine I have also, need new pull starter. There's no name or model that I can tell but there's a emblem on side of engine and on the carburetor. The servos and receiver are Airtronics frequency is 27Mhz AM band (don't have transmitter). Thanks.
