Welcome to the Stovebolt smile
Just one bent pushrod will not keep an engine from running.
If the previous owner had it towed because the engie had lost compression on one cylinder I guess I can accept that.
Does the engine run at all? Many things could be a problem with the symptoms you have briefly described.(need more info) smile

There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.

Be yourself. If you are ever lost, It will be much easier to find yourself if you know who you are!
