Bill, are you sure you have good spark. If you are using starting fluid, assuming you are using it in the right location, this thing should come to life at least for a few seconds. And if it does, then you may have fuel to the carb but it's not getting pass the float.
let me start by saying thank you for the response. Yes I have a good spark I even changed plug ,it’s getting good blue spark and the original plug was giving same blue red spar. And shot starting fluid right into breather with filter off. Then tried a little gas into head just before reinstalling plug. And I’m not getting any firing at all. This machine is my nephews I work on quads a lot so going over basics but now I’m baffle. Took valve cover off and can see vale springs compressing. We do here a noise coming from lower end though. When plug is out seems to havre good amount of compression but I didn’t have compression gauge with me.
