Problems starting 2800 Cummins-Onan gas generator

Cummins-Onan is not going to commit to anything definite on the phone when asked about what could be wrong or how long will it take to fix. They have to get into to it and find out exactly what the problem is. If you want to try the solutions suggested that you can do yourself, that is fine, but in the end you are going to spend double to get this fixed if you pay anyone but a Cummins-Onan service shop because you will eventually end up in the Cummins shop.
