Ii bought a big generator 17 years ago that was plumbed into the natural gas line off of your Dunkirk Indiana company and then you moved to Muncie.The parts guys helped me on the phone and I brought every tune up parts with me to make sure everything lined up. It took them about 30 minutes to find the only 2 things they couldn't find on the phone because it was a 17 years old generator. They told me to bring in the air and oil filter and they searched everywhere and finally found them. Spent some time on the computer and couldn't get a match so they took the old parts and went and searched and found them both. This is the store in Muncie, Indiana. I am not stressed now and I know where to keep going if I need anything else for the generator. Thank you so much for keeping old products in your store
