Tempa Flow ([url]www.holtzmaneng.com)

I also have just fitted a Tempa Flow, this is a gadget that automatically leans off the mixture with rising temperature, this is made possible by changing (lowering) the pressure within the float chamber. A vacuum tapping needs to be added to the carb and the carb vents are all joined together. Both the vacuum and vents connect to the Tempa Flow. Based on temperature the amount of vacuum or atmospheric air is modulated.

Only had it installed a couple of days but engine running super smooth - no 4-stroking when its air temps are hot, which was normal when the temperature gets high (now at 32 degC and 60% humidity).
