i try turning on the quad and does not want to turn on at all i rebuilt the carbs set float height to 21 mm and still nothing i have a 300 jet in it idk if that could cause a issue it just has pipes no airbox and carbs are bored out to 28mm i think unless that is stock im new to this quad got it not so long ago and started doing it not so long ago

 

First check for spark, then the compression. 300's are big for just a pipe but it should still fire. could also be bad reeds, but spark and compression first.

 

No airbox is not helping either. Airflow control is needed with the airbox on as without it might cause an initial lean condition. Check spark and condition of plugs, if they are wet with fuel then probably fouled out. Being a two stroke everything needs to be set just right for the conditions to make them run.

 

well whenever i tip it over and see some gas spilling and bring it back it will fire right up on the first kick so it just does it when the first start up after that its fine first kick any time

 

and the spark plugs on it are new i did a service on it when i got it so i put new plugs and the guy had twist throttle on it then i put it back to thumb idk if changing the mixture from 40:1 to 32:1 had to do anything with it either
