hi deejay thanks again for your reply!!! Over the weekend i couldn't help myself so i started pulling down the kirby today monday and im half way putting it back together. Head bolts were loose as was every bolt and screw. Inside the fuel tank is dried up leaded fuel and some surface rust, its not good. At the moment i have diesel and some nuts and bolts inside the tank by shaking the tank its helping clean it. I have access to new/old never used parts for kirby/tecumseh engines 40 year old new parts. Anyway heres a couple of pics regards steve....
