I have an early 2000 tecumseh OVH130. This is a project my son and I started for fun and is now lost its fun. When I start it I have spray starting fluid in the carb and then it will start. To keep it running for a while I have to have it on full choke. I have replaced the fuel line, fuel filter, spark plug, carb, adjusted the valves. About the valve adjustment I set them to .004 but not 100% sure I did it correctly. Went to tdc and then adjusted both. I am out of ideas.... Thanks for any information you may have.
