Hi, I am Laurin and I'm glad I found this place! I am disabled and spend as much time as I can trying to keep the little bit of equipment I have running. Recently I was rebuilding my 11hp John Deere mower carburetor and was having fits! It would run 20' and quit! I found out why they send 2 needle valves... so, when the seat just falls out, time to try the needle with the rubber tip!! I am back in business! I looked in here for that trick, but ended up finding it at a local Harley shop! Anyways, ty for allowing me to join in!
