92 lt160 quadrunner will only start on ether. It has fresh gas, carb cleaned and rebuilt.valves adjusted. At my last rope with this......Please someone give me some advise....

 

First thing to do is check compression, less than 90psi and it is time to strip the top end down to find out why. One thing with ether, if the compression wasn't bad before you started using it, it will be if you continue, as it washes oil from the bore and rings, causing rapid wear.
