ive always had trouble starting my gpr, it started like 1/5 times and ive just been push starting it most of the time. its just had a few repairs and a new starter motor in, i watched the garage start it 3 times and it was perfect but i still struggle? i usually try with quarter choke and half throttle and then push the starter. The guy at the garage did say theres a nack to getting derbis started, its up for sale now and i dont want it to not start when someone comes to view it! any tips would help cheers
