Hello
Although it is still quite mild here in SW Canada (0C overnight and +15 daytime) I decided to get ready for the cooler temps before they arrive.
I installed a "Thermo-Bob" bypassing 180 degree thermostat,changed out the coolant, adjusted the carb needle valve rings down one notch, and syncronized the carbs. (912UL)
Flew 5 hours around the valley and mountains on the weekend. It was probably a bit below freezing above 5000 feet but the water stayed constantly at 180 degrees, oil between 185 and 220 depending on load (no tape), mag drop less than 100rpm and smooth running down to 1500 rpm on short final.
It really makes a difference to enrich the fuel mixture as temps cool down.
So far I am quite impressed with this thermostat. Noticeably faster warmups.
I suppose I should take some pics sometime. Very nice this time of year with the lakes, mountains, vineyards and orchards. Even a bit of snow on the peaks above 6500.
Cheers
