SLA 265 cooling issue

[ww1putt]

I have a sunl SLA 265 (water cooled) the issue is the water is not circulating and the engine is overheating. Is it possible that the thermocoupler is bad? Where is the best place for replacement parts? Thanks for your help. :cry:

Is the thermostat stuck? Check that first and then take a look at the water pump.

Probably the impeller itself...seems a common issue on other sites more familiar with the water cooled set...scoot dawgs... For some reason most of us here have lo-tech air cooled....but they run!
When you diagnose or get it fixed be sure to enter your findings back here...


:idea: plastic impeller,missing teeth and spinning freely on shaft is my bet
