i am new to your forum and need help,i bought two of these atvs one for parts one runs but the problem is that the one that runs needs to be push started in order to run ,will not start with electric start until the machine has ran for a half an hour or so. then i have a five or ten minute window that the machine will start with electric start. if i miss window of time i have to push start it again until its warm. compression and spark seems good. i believe that it might be in the valve's but dont know the specs on setting them . any advice or help would be appreciated thanks for listening.
