I bought this tractor non running. Went through all the electrical today to get a good spark, cleaned tank, sediment bowl. new fittings and gas line as most of this stuff was cobbled together. Ordered a carb kit and the carb on it has a Zenith bowl but says Bendix on the top part. The top and bottom are definitely different in color as the top is very shiney, bottom is normal drab color of pot metal. It will hit and run off of ether for a few seconds but not stay running on gas. Not sure if the carb is all correct or not, it was very clean inside, i left the adj needle in the bottom of the carb set where it was as they said it would run. Tractor has been running rich according to the plugs. Should i just buy a new carb? Is Zenith even the correct one for the tractor? Thanks for any help with this, it runs great, just need it to stay running.
