Coleman Model 425E

July of 1970 Coleman model 425E was not running when I got it. Put a new gas cap gasket and new pump cup and oiled it with neatsfeet oil. Then soaked inside the fuel tank with alcohol while the check valve was out, then flushed it with water and immediately blew the water out with the air compressor. Did a little pressure cleaning inside the burner tubes and chamber, put it together, fueled it, pumped it and your seeing the result of 1 hour total labor.
