i guess first thing would be to identify what engine it actually is given that the manual showed an incorrect pull start for the engine. what all markings are on the engine? what manufacture was the car? most knock-offs use SH engines because they are cheap and more or less reliable, so i would hazard a guess an SH engine pull start would mount up, but would really like to confirm engine on the truck.
might be an older generic manual for the truck that didnt show an updated engine, or it was an updated manual that came with an older model engine.
