Hello, I have a little problem with the above engine. It is installed in a load-bearing syringe 8/8 from 1962. The problem is the following: After about 1h under nominal load during water transport, the engine goes out and cannot be cranked up. Only when it is cold again (as several hours later) does the whole thing go again, then it runs perfectly again. Until the next hour is over… Is this due to the installed magnet ignition? Does the spark no longer produce any more due to the heat and decreasing magnetic strength? How can I get help? The TS is not used, but should remain operational due to the low operating hours.
