I just replaced my fuel filter regulator and fuel pump. I was able to start it up fine and ran it for a couple minutes. About 3 hours later I came back to it to out everything back together. Once I did this I couldn’t get it to start. I’m able to get it to fir by spraying a Littl starting fluid into the air box. I notice that my fuel isn’t pumping that strong unless I put a battery charger to it. Can someone help me please?
