did a light lap on the valves and lubed guides and assembled the valves. its getting the same head gasket also. and it will run, maybe gallop to the finish line.

A friend of mine told me to turn it upside down and pour a little fuel around the valves to see how good a job you did. If the fuel leaks through, they still need work.
 
yes that is true. I did not do a valve job on it. it had 3 stuck valves so I pulled the head and cleaned the guides out and cleaned valves and seats. things looked reasonably good. could use 2 new seats but I want to try this tractor out first. so many people say just loosen the valves by tapping then or prying them up makes no sense. the guides were full of rust had to pound them out and even tried putting them back in for my curiosity and they were stiff. I brushed the guides and cleaned them with brake clean.
I gave the valves a light lapping just to make sure. then oiled the stems with atf. and now they are actually a little looser than I like. but it will run. will do a complete head job after I see if the tractor is worth it. my dad used to say hopeless case. he was strictly ih.
when doing a new valve job no need to use the fuel test. valve seats are ground to 45 degree's and the valves to 44 degree's. this interference angle gives a good seal and no lapping is done. all lapping is for is to make sure the valve seals... its not for taking the place of valve grinding.
 
THe DC is For Sure ,.. And I like how nimble it is to get along with for any tinker job , And You Can Disc or Rake all day and never get worn out or burned up from the heat . nice handling "ol gent"is what My great Uncle Lesley Bishoff said about the Case DC and I agree . that is why I chose the name for my Handle
