dunno if this is the right forum to put this in

just bought an rc buggy from your online store on the 20th and it arrived on the 21st had a few goes with it and did what the manual told me and ran
the engine in for the first few tanks of petrol (i used the correct petrol) while testing it i moved one of the controls on my remote control. it had something to do with the turning (my remote control is one of the normal ones not the one with the wheel) when i moved it to one side the revs on the buggy dulled down very low. i got concerned and just kept going until it cut out. so i thought ok low petrol but it wasnt that so i put some more in then tried to start it, it didnt start. i then took the air filter off just as it says in the manual and put a few drops of fuel in the carburator. tried again and nothing. thought it was the glow starter so i charged it, set all the controls back to normal went back out and tried again still nothing. next day i done everything again, all things it said to do in the manual at times it wouldnt let me pull and then it would let me so i left the engine for a bit as i thought it may be flooded after a while i tried again putting it upside down and cranking the engine and alot of petrol came out the exhaust. tried again and it still didnt work. at one point it started up for 3 seconds and quickly cut out. i've tested the needle to change the mixture and everything else but since the 21st its never been mobile. i dont know what exactly to do as i have never had one before and dont want to pull parts of the engine out that i know nothing about and ruin it entirely. i'm hoping its not broken already its barely done anything.
