I acquired an Oliver 15hp Model K this past weekend. I cleaned her out and re-tightened the screws and started her up. Took 1/2 can of WD-40 to get her loose. It took several pulls then she started. Ran off and on. I was told to use a 1:32 oil mixture. Day 2 I want out and tried all day but she started and died initially and wouldn't start since. I did put in new plugs and can't get her to fire. I did replace all the fuel lines but still no luck. Any ideas?
Typically a motor that has sat you will need to go through the fuel system from tank to carb with special attention to cleaning all passages and jets,
screens,filters,also be sure all fitting and connectors are good.
Check the spark,should be blue with an audible snap.
