Carb heat muff

[rcarson]

Does anyone know which organization sells the carb heat muff and Fab part to modify the carb heat on the 7? It's a fairly simple device but seems neccesary since all you get on the stock set up is lower cowl heat and the drop in rpm is almost zero when checking. Would like to see more positive response in this Ohio winter.
Thanks.

I had the same problem, this unit solved it...although I'd highly recommend adding some screen door spring wound around the pipe for more hot area....you want the max dwell time for heat exchange, so I even considered closing the slot they use, and just drilling holes in the end plates, then the air must travel further before going up the pipe!

I went with this SS Heat Muff from Wicks with good results.

Here is a picture of it installed on my O-360. Keep in mind, my FAB and heater valve are slightly different due to installing a short Sam James Holey cowl.

Thanks for the replies. It looks like Robbins Wings will get another order.
