Carb HEATER kit was created by hockeystud87
I posted about a carb icing situation that occured in my Rotax 912 UL dual bing carb engine. The conclusion was rotaxes with the carb heat box upgrade that provides cooled air from on top of the motor and carb heat off the exhaust is more susceptible to carb icing over the air filter that are directly attached to the carbs pulling warmer air off the back of the firewall area.

My question is has anyone used or have experience with the carb HEATER kit i linked bellow (this is a different product that the carb heat box)?

This bolts directly to your bing carb between the rubber boot and the carb. It draws coolant into a metal block that then transfer heat into your carb housing. Makes the metal warm. The idea is that you loose no engine performance cause you're not changing your air temperature but not allowing for any ice to form cause the carb metal surface will be above freezing.

Hot coolant carb heat systems have been a round a long time and work well. Better than many hot air systems that some aircraft Mfg's use for their plane and like you said it doesn't inject hot air directly into the carb.

Roger,

Do you know if there have been any reports of issues with these carbs on hot days?

I have convinced my self that I am going to be purchasing the carb heater kit. But am concerned on what happens on a 80-90 degree day, will I cook my carbs if I use these?

I live in the Pacific Northwest and moist and cold is the name of the game here. So I think these will be a great help with the addition of the carb box. Gives me more options at only a pound or so weight penalty.

You'll be fine on warmer days.
You could wrap a burrito in aluminum foil and drape it across the heaters and when you land it would be all warmed up for lunch. LOL Just kidding.
