[AT] Need some help, hard starting CR950 Briggs

[Cecil Bearden]

My 2017 Polaris Ranger will not start below 50 degrees without Ether if 
I use no ethanol gas.  I use the cheapest unleaded available and it 
starts and runs fine.  Of course it is EFI.  I have worked on the small 
engine EFI in ATVs and I really do not like them...  I have no idea if 
the computer is working...
