Hello- I am new to the stationary gas engine scene. My family has always used IH farm equipment and I have restored a few Farmall tractors. I have aquired my grandfathers" McCormick Deering vacuum pump and milker set-up. The pump and milker unit is still in very good original condition. I would love to find a nice original LB engine with original paint to mate up with the vacuum pump. Is it very common to find them in this condition? I have inquired on several that are for sale but they have all been restored. I would pay as much for a nice original example as I would for a restored model. I do not plan on restoring the vacuum pump therefore would like to find one to somewhat match. Any thoughts?
