Reply To: 1939 Johnson 5hp AT-39 Running Hot

[Swarlos]

Thanks for the reply Boat House.  I know he’s had it since he was young, so I guess his dad bought it for him new.  I’ll have to ask him.  It hasn’t seen much use these last few decades, but it would give me a smile to get it back into proper working order.  It’s a project that I’ve taken up for a few weeks every year or two for the last 6 years.  It seems to be running pretty well now, but I’m still nervous about opening it all the way up.  Since there isn’t any kind of high temperature alarm, how would I know if it’s getting too hot?
