Hello,new member here,i purchased a ez track 225 4 yrs ago,the mower doesent,ever have 70 hrs on it..begining of yr it craped out ,dumping fuel into carb,the john deer shop said it was a sheer pin broken..they fixed it (550)and all was good for 2 months..today the mower just cut off while i was running it ,look like it ran dry,i filled her up and the mower wont stay running.It will start with out any issue but just cuts off in a few seconds...I realized the mower will run if the choke is on n drive but as soon as i try to take choke off it dies.....help
