Hello, first time on the site and though I have a pressing issue I need assistance with, I kinda found myself setting back and reading a lot of posts - date didn't matter - as my interests are right on track with the vast majority. I do think I am going to receive a lot of excellent and useful info from you all. Here's my problem: I have an Ariens self-propelled lawnmower that is approximately 1 year off the lot. It is a fine machine but yesterday it started and then immediately shut off. I checked everything possible externally and nothing seems amiss. I checked the fuel and after replacing the cap, I cranked it over and it fired right away, ran for appx 2 seconds and died. The only way I could then start it was by removing the gas cap and replacing it, the end result always being to start and run for two seconds then die. Any ideas team? I greatly appreciate any advice, suggestions as I am not all that smooth with the finer points of machinery. Thank you
