"hi,
last week i wanted to start my engine (first time this year) but it ran only on 2 left cylinders. there was no spark on two right cylinders. after unplugging the right thermo switch the spark appeared. i re-plugged the switch and it seemed to be ok.
on the water i got several times a warning signal and the engine run on low rpm. but oil level was ok.
may it be the thermo switch or a cooling problem?

kind regards from Poland
Jaroslaw"
